I did it, today I went to Awesome GTI here in Manchester & had the DV changed. I also had the S3 put on the rolling road which gave me a bit of a shock....
Revo say stage 1 on the S3 (8P) should take you to 300 BHP. I also have a Neuspeed CAI & Milltek cat back non-res exhaust which I was told gives a few extra BHP.
The readings came back as:
Run 1
Max Power = 278.32
Max Clutch Torque = 319.35
Run 2
Max Power = 285.67
Max Clutch Torque = 313.35
The lad from the workshop handed me the print out & said "nice car, 286 BHP." I was like, huh, is that it...?!
When I queried it saying Revo publish 300 BHP (the tuner who did the work on mine said he estimated mine to be at approx 310 BHP with the exhaust & CAI) they said that the figures they publish are fly wheel figures and not power at the wheels.
Is this right? I was expecting to get a figure of at least 300 BHP at the wheels & feel a bit cheated now
Don't forget two things....
Firstly,the difference between the best quoted figure,and what you obtained,is only 7% at most,and is within the sort of variations you get for rolling roads,fuelling,ambient temps etc.
Secondly,after a remap,the ECU will adapt over a few days.
Either way,not bad results at all,and the difference between 290bhp and 300bhp at 7000rpm is something that most people simply will neither notice,nor get a road long enough to do so on.
