Like the title says after swapping to a TVS blower intake I was having issues with the trans shifting early and having it stack shifts together. At times it would be in 4th gear before I cleared an intersection at light throttle. To eliminate the issues I had to zero the VVT tables.
My guess is that it has something to do with MAP but the TCM has no provisions for MAP vs. anything that would vary shifting.
Does anyone have any ideas on this?
Thanks
