Default Possible Tune Problem

Hey guys, I normally don't post in here because i don't tune my own truck... but after i swapped out my trans and got a new tune for it, its been acting up.... The problem only happens when i go WOT at 30 or so... it hits the limiter just before shifting, however it doesn't do this at WOT from a stop... Do you think this is the tune or a drive line issue??

Thanks

LES

and you're running a new FLT in your truck? that's usually what I notice when a tranny is fixing to go. It's possible that your rev limiters and shift points need to be spaced a little bit more.

mine's been doing the same thing... just chill on the hard punches from a roll... rolling into the throttle in 1st and letting it shift into 2nd on its own, it wont do that. I believe my problem is in the tune also..

kinda seems like the limiter is to close the shift point... seems like a bump in the limiter would fix the problem

I had a problem kinda similar with my stock setup, i had accidentally changed the full throttle shift speeds too high, when you do that, if you change the 2>1 too high, it will hit the rev limiter before it shifts, you have to lower the speed
