I might have had a problem with and SCT tuner one time. It happened when I might have introduced a power fluctuation while uploading the tune. I might have done this by getting bored and playing with accessories. Just sayin'.
I was letting the auto shift but it was breaking loose on every shift. When I feathered the throttle get traction it would sometimes upshift again. That gave me a 13.6 or so. :(
No vids. Made a boatload of runs but I can't break 13.1 yet. If I spin off the line my 60s are 2.1. If I don't spin my 60s are 2.1! Through the trap I am consistently 109mph, still in third gear, and still have 1000rpm til redline. If I push it into drive it still doesn't hit fourth...
