2008 auto cam, headers, intake 461rwhp. The problem is while it is in Drive, it will not shift out of third at WOT. Will rev all the way to the rev limiter. In sport using paddle shifter. Its shifts fine. Shifted fine before cam and extra horsepower. After the upgrade in horsepower the problem showed itself. I have had it tuned and still does it. What do you guys think or have you ever heard of this problem. Drives perfect at all other times and conditions.

Only suggestion is your tune is not correct. EnglandGreen is not too far from you - Google his location and give him a call.

Review the tune and check for trouble codes.

Sound like the TCM is not tuned properly. (Transmission Control Module)
