I have no idea, tranny maybe? how long have you been running that tune... my 135 rocks way harder than on the 90 or 70. Well I cant say that for sure cuz I have never ran the 70 but I dont see it ripping harder than the 135.

you will just have to drive it normal for awhile. What setting did you have it on before the 135?

i would let it learn but i'm guessing your TC isnt in the best of shape by the sounds of that! have you changed the fuel filter lately? just because the RPM's go up doesnt mean its getting all of its fuel!

I have had strange things happen when i took my programmer off my truck because i was going to the dealer. It did something similar. Just drive easy for a little while and it should be ok.

My qs2 doesnt ask if I want to set for a relearn function either. I just drive it normal for a while until the rough shifting stops then its WOT.
