My understanding is that with the Gti-R all you'll really do is make more heat which might even see you with less power.
You could get it RR'd and see though...

Well Perfect Touch optimised my GTiR at 1.35bar when they set up my Unichip for maximum power. They seemed to feel that this was the realistic safe maximum for my set up, and I'm very happy with the results  . Phil

It really depends on how the car is mapped (you could run less advance and more boost for example or vice versa)- but 1.3 bar is the limit on that turbo IMO. You'll get very little from going higher. You really want to raise the boost until you start to get a diminishing increase in bhp and then back it off a bit. There's little point in ragging the nuts out of the car for an extra 5-10 bhp.

Its not all about bhp tho suba. Its about the extra torque aswell. Ross

Well that's pretty much what Rob at PT did with mine Si . I asked for 1.3 bar, but he felt that 1.35 was quite safe on my set up, and the extra 0.05 bar was worth it for the extra driveability . I have to say that my car flies on the high boost setting, especially in this lovely cold weather  ! Phil

It's the same high boost setting that I have on my GT28R....
Ross - yes you can get more torque by slapping some overboost / midrange but I dont feel like this makes the car more driveable and you're going to have more heat to deal with etc.

Well been out this morning and increased the boost So the car is boosting 1.35 midrange and droping 1.1 by 7k  Also the AFR has improved to hold 11.4/5 mid dropping 11.1/0 at 7k  The car does'nt feel any quicker but it feels there is a liitle bit more torqe midrange  Something for Ross Checked the spool in fifth and can get 1.35 just under/touching 3k Ben

Getting boost is different from the car getting on torque.

Ross Thats right thinking of that Though coming onto boost at 3k, the torque doesnt really kick in hard till 3500/600k Ben
