For the tuners here;
Seems after a 5th revision, the guy who was tuning my car at VMP was fired, and left me high and dry with a crap tune. Crazy amount of clutch protection, idle timing ATDC, erratic idle, etc. Anyways, long story short, I had to revert to a pre IMRC delete (cause I went with a 18+ intake manifold) tune just to get the car to run well. So if you guys could indulge me i have a few questions, since i'm running the intake and the CEL is showing the typical IMRC out of range/not functioning p-codes. My tuning device allowed me to raise the RPM limit, 2-4k ignition timing, 4-7k ignition timing, and GLOBAL timing, MAF percentage so;
1. At what RPM does the IMRC goes full open ?
2. What other compensating factors is required when going IMRC delete? ignition timing ? Cam timing ? Both ?
3. Is it ok to run 'as is' for now? There's just some slight bucking under 2000 rpm, and sometimes it stalls when coming to a stop.
Thanks in advance
