If you didn't disconnect the exhaust back pressure sensor, then I'd try returning your truck to stock programming and then retuning it with RaceME tuning again...just make sure your batteries are holding a full charge. Low voltage can cause all kinds of programming issues.

Thanks Ray,

your expertice ice is second to none... I fully charged the batteries returned to stock and returned with RaceMe tuning all is great...

again,, thank you very much. I look forward to doing business in the future, especially when custom tuning becomes available.
