[QUOTE="XP900, post: 16528474, member: 199546"] My idle issues are gone... I had the car tuned with the new VMP Gen2R budget kit (VMP send me a tune for the kit but my idle issues were still present after swapping in the new SC) Anyway after Speidell Supercars tuned it the idle issues are completed gone...during startup and even slowing down at lights. My car is currently running better than it ever did but I don't know if it will last - idling issus always seem to just pop up out of the blue and I changed a lot of parts (now all spare parts) trying to figure it out with no error codes popping. Either my tunes were messed up (an I reloaded them several times and used different tunes and still had the same idling issues) or the PCM itself settled down and fixed the issue. I don't know...tuner said he had no real issues tuning it...and took it for a long test drive too when he was done. So maybe that was enough time for it to recalibrate?? The tuner had a 2009 Shelby himself so he was pretty familiar with the engine and tuning it. He definitely tuned it the way I like ...smooth, no jerking as pedal increases - only a steady increase in power and torque. Better than the VMP tune they sent and better than all my BAMA tunes.
