08 6.4 EGR *** ******..SCT tuner purchased in 09 Dealer is trying to find issues with truck stuck in limp mode, I returned tunes to stock and took it in, He flashed the TCM and now SCT tuner wont program tunes because SCT don't support tuner anymore and dealer says he cant go back on flash that will be compatible with SCT tuner. Now what any help would be greatly appreciated.
