Best way to tell is to log a 3rd gear wide open throttle pull. The link below has directions on how to do that. Posting your logs in the support forum on n54tech should get you some feedback on how the car is doing on map 2 with only a jb4 and intake. I'd personally also be interested in looking at it since I'm having a few issues with my jb4.
