Hi all,

Car's an MY06/07 STI.

What results would a remap give if I kept my standard STI downpipe..?

Currents mods: Green cotton panel filter, H&S system from downpipe back with no mid-cat or resonator. I'd also fit a Walbro fuel pump prior to map.

I strangely don't particularly want figures over 320-330bhp, but I am a big fan of torque. I'm just looking for a smoother drive, better delivery & mpg and a touch more power to keep these pesky hot hatches off my tail. Oh, and I value reliability.

Would be looking at the Likes of Bob Rawle or Mocom to do the work. Also, is there such a thing as a switchable map for the 06/07 cars so that if any warranty work is required the dealer can't bounce it?

Cheers in advance.

Thats basically a PPP remapped (with the fuel pump) will get 310-340bhp 340+ftlbs

v8voodoo

Yep, a remap to a safe figure as per the ppp, with nice lumps of torque and smoother curves but without the ppp price.

Worth doing? Anyone done similar? :scratchchin:

cster

I got a PPP on my Spec D - was OK.
I then got it remapped by JGM without any mods and it drives noticeably better.
So go for it

One of the guys on the wales section who previously owned an my06 sti with similar mods and mapped by Bob rawle claimed circa 380bhp/390ft.lbs, im doubtful.

Mine in a similar state of tune as it was back then got 333 / 356 with just an air filter, back box and remap

v8voodoo

Hmm, it's starting to sound like a plan. Did you find it smoother than standard with boost coming in earlier and more progressively? Can I ask who did the map at that stage?

Another question, is the remap actually detectable by the dealer?

dynamix

Maps are always detectable - they would only have to drive it to know that it has been enhanced. It is very noticeable from a drive point of view and if it went bang, then any modifications will allow them to wriggle out of it.

Mocom Racing did the remap at the stage.

Hence I wondered about dual maps. One for normal use, the other specifically for servicing and/or warranty issues.....

the figures are all a load of blx in my opinion for example

on here you've had the following
310-340 (my estimate)
380 (LOLOLOL)
and 333

Frankly when it comes to power wheel horse power is the only true figure you can compare as all of the others are guesswork!

saying that DO IT it makes a massive difference. Mine revs smoothly to about 7k now where as it would dip and trail off about 5.5k before!

dynamix

but not all dyno's produce the same wheel horsepower figures.... so which is blx?

can of worms and whatever you think they are the figures are more than the std factory power. peak power means squat aswell - it is not that part that alter much in the remap process - it is bringing up the area under the curve and that is what makes for a faster car.

edited my post and dynamix your spot on!

I should have said ..... at least with whp (rollers/hubs) you've got a fighting chance at having a comparable hp figure, Still massive variations!

288hp323ftlbs at the wheels with a panel filter, pump and sports cat.

You would be on for 280hp300ftlbs at the wheels I reckon. Add to that what ever dubious formula you care to choose. By my reckoning 325/348 fly is a good estimate.

I think this remapping lark is like a bungee jump.

You're standing on the edge of the platform, you want to do it, you know it'll feel great, but it's a bit scary and there's always the remote chance the bungee might snap......

Just get it done It's worth faff all in the current used car market anyway

Really transforms the car and the power delivery so worth doing. I do have a decat in addition to your mods, but as stated you'll still get marked improvements with the standard cat in tact.

I wouldn't bother changing the fuel pump, it is unnecessary on a 2.5ltr sub 400bhp. Something I found out to my cost after fitting it

I would recommend you get better spark plugs though, should always be the first thing you do IMHO.

I think you've already answered your own question TBH. Keep to your goal and the small amount of mods needed and it will be very cost effective.

If noise is an issue then decats and going up to 3" drainpipes won't be on the list.
As for driveability, even going for something like a 20g is surprisingly smooth with bags of torque.

As a bonus of the extra torque, you'll be able to get something bigger than that 1 person caravan

I know this is taken from Andy's website but it doesn't read right at all.
For a start the STD BHP is 280, and PPP comes in at 320.

Mikkel

I was thinking the same thing... looks like a mix of 2.0ltr and 2.5ltr tuning info

Level 2 onwards sounds about right.

Sounds about right mine rollered at 275hp (without the decat or sports cat downpipe)!

Hi. My cars a 2006 2.5 WRX with a standard downpipe with a afterburner decat & centre with prodrive backbox, if i had it remaped what bhp figure would i be looking at ??

Cheers Stuart.

PantsUK

iTrader: (1)

1million ... but that's bhp not whp

Black-Hawk

iTrader: (4)

Close to 290.

not with standard downpipe still.. more like 280 give or take a bit the torque is the main gain..

come to think of it a GB270 the other day I did ended up 280bhp and 340lb torque with standard exhaust still and is basically a 2.5 WRX with PPP already.
