Now my beloved car is 3 years old and the warrenty has ended I'm in a "more power required" state of mind,
I like the way the car sounds at the moment so i dont want to change the exhaust so was wondering if anyone had just remapped their PPP'd sti?

What type of power/torque gains did you achieve?

 

Just adding a 3 port boost solinoid you should get 310 - 320 bhp & simular Ibft torque. The biggest difference will be that the car is so much stronger in each gear & it does not run out of puff at 5.5k rpm as the PPP does but pulls up to the redline. Some people get more although a lot depends on whos rolling road figures you quote.

Very recently had my 03 STi PPP remapped by TSL (Richard Bulmer) and I retained the Prodrive exhaust. Well worth doing, the engine is smoother, has noticably more pull and in like for like driving, the fuel consumption is every bit as good. With the PPP, if I accelerated reasonably quickly, the Knocklink would often flicker the greens (I've also had a rare orange) So far, the Knocklink has been quiet which shows the extra smoothness.
Just before the remap it showed over 300bhp but with a poorish 288lbft on Power Engineerings rollers. Although it hasn't been back since, I would expect close to the TSL 333 figures.
