I'm toying with the idea of getting the PPP fitted to my Sti, and i'm just wondering if anyone has any info or opinions which i should look at before signing on the dotted line!

I've heard that it will increase my mpg (but let's face it, you don't buy an Sti to worry about that now do you!!) and i thought i'd get some feedback straight from the horses mouths or so to speak!

I'm pleased with the standard performance, but coming from a large engined V6 i'm still trying to get used to the HUGE flat-spot below 3.5k and i've heard that while the PPP doesn't get rid of it, it reduces it massively! I haven't had any 'traffic light' starts yet, but i'm not that confident that i could launch that quickly if i needed to. I'm conscious of giving it large revs to get past the 3.5k problem, and damaging a drive shaft or something?

Thanks in advance and please don't take the p***, i'm new this Scooby malarky!!

I have a PPP STI but I have not driven a non-PPP STI.

I only have issues with below 3500rpm performance when pulling away in first. Sure if you launch it you will take off but I struggle with slow controlled launches. Probably just my driving though....

At 3500 all hell breaks loose if you have the loud pedal pushed to the floor. The performance is great but by 6k it has peaked. I have my shift light set to 6500 but I think I'm going to reduce it to 6k as there is little benefit to staying up to 6.5k or more.

I'd love to try a TSL 333 mapped STI to feel the difference in power across the rev range.

I have a TSL mapped STi and it doesnt run out of steam right to the limiter. The power delivery is very linear.

The PPP wont stop your turbo lag and the car will never feel like a big 6 or even a hot hatch when you pull onto a roundabout for instance. There will always be a delay up to the point when the turbo spools up. I reckon without loads of revs and dropping the clutch I could be out dragged by a push bike when pulling onto a roundabout from a standing start.

You will only hear good things on here about PPP of that im sure and it will transform your car. Go to your local dealer and drive your car and then a PPP car back to back. Then sign on the dotted line like everyone else does

r32

I ran my STi (MY03) without PPP for a while, power comes in very quickly at around 3600 or so, and the delivery is very sudden. With PPP I find the power is more gradual and starts around 2800 and is much smoother. It destroyed my fuel consumption, but its well worth having done. Transforms the car. Just amazing .....
Do it, and keep your warranty too.

p1doc

then get the tsl 333 which is faster and more driveable than ppp all imho

Destroyed your fuel consumption???????

You mean it can get worse?????

Is this under normal driving or just when you're pushing on?

I seem to be returning about 19.5 mpgs over the whole tank - and that's with quite a bit of Driving Miss Daisey! I was returning about 24 in the R32 with the same driving style!


How much harder does the PPP car charge under full boost than the standard one?

sKunk

I really struggle to get 200 miles out of a tank.

Best milage I've had is around 220, worst was 60 miles to the tank on the track

MY 03STI Ecuteked by Bob Rawle (peaking at 1.55 bar now)

220-280 from tank

Crazy car now it''s been mapped, raw sound, silly performance, pulls past 6,500 without a second thought..

Plus it's cheaper, but my warranty is a no go....

Chris,

Had my STi 03 PPP'd after 6000 miles. Pulls a lot harder and is generally much nicer to drive ,particularly round town due to the smoother spread of power. Rag it and it will use more fuel (15-18 mpg, more power uses more fuel - simple), in normal driving I'd say it's the same or slightly better at about 23 mpg on Optimax. I've driven TSL's 333 demo and it feels cleaner but only on a short run so I couldn't say it was noticeably quicker. If you're going to spend money on your car can I suggest getting the Prodrive springs and geometry sorted first, I had my PPP first but with hindsight I'd go for springs first.

Cheers, Diccy.

Mosquito

Firstly, thanks for all the feedback!

I appreciate it all!

I've just had a baby, so the ride cannot really any harsher than the standard one is now - does fitting the Prodrive springs do this?

Plus, while i can afford the 2k for the PPP, i can't really afford to spend money modding the car only to find in twelve months or so something has gone wrong with it and it isn't covered by the warranty (if this makes any sense!!??). I'm not suggesting that any of the re-maps/mods would CAUSE the car to go wrong, but if it did go wrong- and mechanical things can do!- i think Subaru would use anything they could not to repair it under warranty!

I think you'd be mad to go down any other power route than the PPP on a brand new £25k car. Keeping the warranty must be worth the extra you pay for the Prodrive stamp.

Sounds like the PPP is the best option then! It's less risky should anything go bang! BTW The R32's throttle was deliberately set up to deliver the biggest response over the first couple of inches of travel to highlight the contrast betwen the naturally aspirated V6 and its turbo charged competition. Driving around the flatspot off the mark is fairly easy: just let the clutch out sharply at fairly low revs, but modulate the throttle to keep it around 3k and then floor it when the clutch is fully disengaged...oh, and hang on! :-)

Chris,

Ride is greatly improved on Prodrive springs, your baby will appreciate it. Gets rid of jiggling and strange bounce. Honest. I have a dodgy back and was thinking of getting rid of car on std springs as it was hurting, no such issue with the Prodrive ones.

Diccy.

Mosquito

Does it handle better too?
No that i have an issue with the handling to be honest! - That's why i was thinking of upgrading the power first!

Better handling and a more compliant ride - now that could be a godsend!!

automodellistagt

my sti ppp is only sluggish upto 2k, by 2.5k she gets going. im more dissappoited with the flat spot nearer the top of the rev range which i think might get sorted by putting on a better exhaust, like the afterburner. what does anybody think? by 5,000 rpm im bored, even hough i know that peak horsepower is at 6k

Have to admit, I don't consider PPP good value when I could have got more power and driveability for a lot less!

Hi - been reading Bobs dissitation with interest - is he a commercial tuning co. or does he simply work from home on request?

What is your base vehicle and what are the proven torque and bhp figs now?

compshack

I've had two STi'S one a 03 with 3rd party mods (Scooby sport) exhaust bigger fuel pump and re-map by pat. The overall effect was staggering allbeit a bit on the load side from the exhaust.
The second one, the one I have now is a 04 with PPP (May) the differance before and after (non ppp to ppp) I would say is more noise but just the right amount, initally more power coming in lower revs and with the prodrive springs and 18" wheels the handling is as good as it gets IMOHO.
3000 Miles later and the car is really moving. I would say it's as fast if not faster than the 3rd part mods and yes I still have the warranty.
I have driven the TSL car and to be honest it didn't really do anything for me. I think the mods are so similar performance wise if you have a UK car I would go for PPP.

sKunk

For me 4 - 6k is pretty much a blur in 2nd & 3rd. Granted this is the most powerful car I have ever owned and I've only had it a month or so but it doesn't hang about. 6 - 7k I do notice a difference and that's why my shift light is at 6.5k but I'm thinking of dropping it to 6.

I do want to drive a car with a remap which provides constant power all the way up to 7k

I have the MY03 STI PPP with Prodrive springs and 18in PFF7s and th overall package is very good. Handling and ride whilst on the firm side is still much more comfortable than my old MY00 wagon. The only gripe I have is the "buckaroo" effect when starting off from standstill if you don't get the revs/clutch right. My dealer said Prodrive are working on a theory where a loose heatshield may be causing a rattle which is picked up by some sensor and interferes with the fueling or something along those lines. Anyone else experience similar?

I've just picked my STi from having it's PPP fitted this very afternoon. After running it in until it's 1000 mile first service, I then did just over 500 miles whilst waiting for the PPP to arrive at my dealers (the excellent T H White in Cirencester). During this period, I spent my time getting accustomed it how it went.
I picked it up at 5:30pm and I've still got a grin a mile wide. For me, it's like getting another new car 2 weeks later which is even better than the original.
No chance yet to check the mpg side of things, but with this much extra fun, who cares. Highly recommended.

Bob is BR Developments, he does his mapping from home (Swindon area), while Branco covers the London area.

My car is a 2003 Eu STI, with
H/S Wide mouthed Decat downpipe
Prodrive back-box
STI panel filter
3 point boost Soloniod,
Bailey VTA Dump Valve (prob going back to normal soon).
Knocklink

Power? have not R/R'd the car (Bob maps the car on public highways, not Rolling Roads) but it's quicker than the Powerstation map I had, and that was 290bhp on their rollers.

Chris,

Improved handling with Prodrive springs goes without saying, I was only commenting on the much improved ride.

Automodellistagt,

Suggest you get your throttle angle checked that it is programmed properly with the new ECU. The dealer that fitted mine screwed up and fortunately I ran into someone who knows what he's doing and sorted it for me. Quite an improvement, my ECU thought the throttle was at 91% on WOT and was misreading the load which could cause detting as well as other misbehavior. Have my red light set at 6500 and it gets there and beyond very quick without any tailing off.

Good luck, Diccy.

automodellistagt

i noticd that the earlier uk's classics were similar to this 'no pull' throughto the redline and thought breathing was the problem then. Where do you think i can have the possible problem diagnosed? im in sussex btw

D1CCY

Auto...,

Havn't a clue in Sussex, I'm up in Hull. Can only suggest a good Subaru dealer (they're supposed to do this for PDI checks so they should know how, should cost about £30). Alternatively a specialist like TSL. You can guarantee their 333 would be set up properly, having my PPP sorted made it feel very similar to the 333 for clean pick up.

Hope this helps,
Cheers, Diccy.

Mosquito

Thankyou all for your input and giving me some insight into the PPP!!

I think it's sold, now all i need to do is not spend anything for a couple of weeks.........

GRIFF007

Thanks Kyle

Mark_S

Branco is doing mapping now!, thought Bob did all the mapping and Branco all the driving????

SirFozzalot

I'm quite intrigued by the majority of people with PPP saying that the power ends at 6000rpm. My MY03 STi (TypeUK) hasn't got PPP (yet ) but it pulls right up to the redline no problem!

sKunk

Yeah, but the PPP remaps the engine to produce 300+bhp peaking lower in the rev range.
