Recently installed oversized tb, skunk 2 im, bc 3+ cams, and vafc on my friend's 95 teg gsr. After we had it tuned on the dyno occasionally his revlimiter will engage at 6500 instead of 8000 rpms. Any suggestions, thanks.

 

anyone??

 

yeah sounds like the ecu is trying to run in limp mode does vtec work during this time?

 

Yes, Vtec kicks in at 5400 and runs untill 6500 when it hits the revlimiter.
