So I have a vmp tune and I noticed this issue last year and thought I had it resolved but testing at 100mph+ isn't an easy task. I know its in the tune because the car does seem to shift into 4th and 5th when using half throttle. I tried working with them again this year and its still an issue. Almost makes me want to go to another tuner.
Has anyone experienced this issue before where their car wont shift into 4th at WOT.
