I finally bit the bullet and got an Accessport. Car is still stock with the exception of the GrimmSpeed intake filter. Flashed Stage 1 91 with normal wastegate option. While I like the smoothed out throttle response, the car feels slower. I noticed that peak boost is below what I had recorded before - car display showed max. as 21.9 psi. With the new map, I now usually see between 11 and 12. Granted, these days it's been very cold, so I would expect to see some impact, but not in that direction. Besides the tune, nothing else has changed. I did some logging as per Cobb's requests (3rd gear pull from 2500 RPM to red, attached (Excel sheet, rename back to xlsx due to restrictions)). They came back saying I should check for a boost leak but the car is almost brand new, only 14k kms on it and it seemed quicker on stock. Any ideas?
