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

It’s not that simple. It’s open at map 14 and a given load looks like this and a lot more

Don't you just tick IMRC CLOSED and copy everything from IMRC OPEN to IMRC CLOSED ?

Come to find out, this is the incorrect way of doing it.

Went with Diablosport/Holley. There canned tunes will rival LUNDS in overall power & drivability.
