Had my twintercooler fitted yesterday and was wondering if anybody with the same experience could advise?
My car is stage 2+ and at the last rolling road prior to the intercooler fitting was running at 278bhp and 320 lbs/ft torque.
Yesterday I had a full service and cambelt/waterpump change with the intercooler fitting.
The 1st rolling road after fitting was 280bhp and 308 lbs/ft torque, the 2nd was 281bhp and 313 lbs/ft torque and the 3rd 281bhp with 214 lbs/ft torque.
I have never used anything other than V-power, so different fuel is not in the equation.
The bhp wasn't concerning me, but obviously the torque was. They did say it will take a few tanks of petrol for the ECU to adjust, is this true or do I need them to look at another map?
Forgot to mention that I also changed from resonat to non-resonated, but surely that wouldn't have caused the torque drop?
