Re-mapping STi PPP - worthwhile?
Have a blob STi PPP and am thinking of a remap. Want to leave car as it is (i.e. retain sportscat and back box) so I have no emissions issues. Would guess I might get to 320-330 bhp and similar torque. Am i correct i thinking the PPP-->TSL333 conversion is just a re-map?
Anyone been down this route? Worth it?
Cheers

We've always made substantial gains when mapping PPP cars. There's nothing wrong with the way they did it, as it was intended for mass market applications. Custom mapping is the way to go with these.

just the clarify the car is standard + ppp.. so standard ppp exhaust etc..
I have done a handful of ppp standard cars, normally the exhaust has been changed.
They make a big gain in torque and throttle response and useable power.. if you were to compare the before and after graphs you will see the area under the graph is larger but at higher rpm where peak power is the exhaust is restricting the power more than with a better exhaust..
you will notice a gain.
If you went for TSL333 then it would be me mapping it..

My freaind had an STI8 ppp a couple of years ago and added a Green panel filter, better exhaust and GT spec manifold and got 365/365 with a remap from Richard Bulmer.

OK, have had re-map done today. Will post up read-out tomorrow (need to scan in from work). Looks to be a bit down on torque below 2500 rpm (compared to std PPP literature, forgot to get the 'before' dyno read out 
,though this is not really noticeable when driving) but hits a peak of 330 lbft at 4000 rpm and 332 bhp at 6000 rpm. Peak boost is a smidgen over 1.4 bar. Does these sound about right?
Would the lower torque figures at low rpm manifest as lag? Car feels noticeably but subtly quicker. For info the peak power before mapping was about 306 bhp (people have said before that it seems fairly quick for a PPP car).
Only mod I have from std PPP is an afterburner de-res centre section.
Any comments (esp JGM
)
Cheers

My PPP didn't make anywhere near the figures promised in the brochure.

shame you didn't get a before graph.. but where was the 306 recorded?
you appear to have questions that who ever mapped it should have answered?
Post the graph and it might be easier to discuss, boost is fine, you can run a tiny bit more than that but not always necessary.
Surprized it only feels subtly quicker. . as 30bhp should be very noticable.

as I could be told anything and know no better. Have just got back from a run.....................and yes I'd now revise my opinion from subtle but noticeable to very noticeable esp above 3500 rpm. Think I was taking it easy on the way back home. Need some dryer weather though, certainly wheel-spinning more than previously 
. Was done at Dyno Demon on Wirral. I should be able to get the 'before' print out.Appreciate the comments and will post up dynos asap

In my experience it pulls better from low down, and basically pulled like it was one gear lower between 2 and 3K revs.
Also ran cleaner at cold engine temps (which surprised me).
Not having a pitch black exhaust looked nicer too

Hmmm.... interesting.
My V7 had an FMIC fitted and made around 340 bhp, but managed 1.6 bar unless really cold, then hit 1.7, and it felt ballistic after the 280 bhp it had before.
You'll now find you are on the slippery slope to 400 bhp.

My PPP with de res and afterburner and panel filter gave 250 at wheels (AET rollers are very accurate )
After fitting cold air induction, Simtek and 3" turbo back I got 318 at wheels with tubular manifold. Now running ported standard manifold and running 321 at wheels (but needs mapping for this as spool is now quicker so needs more fuel bottom end
)
All mapping done by JGM (thanks Simon) and always felt quick as a PPP, proved this chasing some 380bhp cars
But now with Simtek etc its really quick
Please note its still on standard turbo and figures are from wheels, (flywheel has to be a guess unless you remove engine )
