Help! I bought my 2006 300c 5.7 with a blower and a custom diablo tune on it. It has been running and driving fine since I got it, but ive done a bit of work to it since and then recently I had it wiped of the diablo tune, and had a custom hp tune done at a shop (I won't name the shop, but its as reputable as a shop gets, it's just Sunday and they are closed so I can't ask for help). So that hp tune has been in my car and running great for the last couple weeks. I've been sending my tuner log files through email, and he just got my first revision back to me last night. Loaded it on to my car, it was idling rough but in drive it was fine, and I coasted down the road about a half mile (never gave it more than 10% throttle) and it stalled in 3rd as I was coming to a stop sign. Won't start. Sounds like it wants to, but sputters and won't run. So I flashed the tune that was on it before last night, and still won't start. Has anyone had this happen? What should I do?
