When we went to tune the car on Tuesday we had issues for a long time trying to balance the voltages at idle and just above idles and when coming off throttle.

We eventually balanced the MAF's by rerouting the pipe work down beside the charge cooler pump in the driver side/left side of the front bumper.

Once we got up and running we found the car to only be producing 7.5psi.

Our setup is as follows:

Stillen SC kit
25 row oil cooler
9lb pulley
MXP Exhaust
Decat/Test Pipes
Custom Tune from TDI North

My theory on the 7.5 psi is the decat/test pipes creating no back pressure. Would anyone tend to agree?

I have CSV file from logs from the day after doing a few pulls but i cant seem to attach it here?

Can anyone chime in and let me know what they think? I would have expected the car to do well over 500hp at the flywheel.

Cheers
