Hello,
I have a 2010 Dodge challenger 5.7L that has a 270 comp camshaft, stage 6 heads, magnuson supercharger,
kooks headers, full 3" exhaust, 85mm throttle body. I am having problems with the idle surging, and also a surge when you are cruising just barely on the throttle. when either of these happen the throttle is opening and closing and the timing and AFR fluctuate up and down. The AFR is usually fluctuating between 13-19. It also has some issues with the cold start settings. Anyone on here that can modify my tune to fix these I will pay. I have had it tuned twice and neither professional tuners can seem to get rid of it. I have tried reading through some fixes I found here and have made it better but not got rid of it. Any help would be appreciated.
Thanks
Josh
