Hello guys
First of all as you might already know I am from the Middle East, and I own a 08 Chevrolet Lumina SS 6.0L V8 L98 4speed auto M32 4L65E trans.
I already have a custom tune done by my friend and would like to have it checked/modified if needed. My friend doesn't have that great knowledge when it comes to non Jap cars so he didn't touch my trans tune.
My main issue is when the car shifts from 1st to second the shift is kinda gentle and I feel that the car dies for a while then builds it's power back up. ( I hope you know what I mean)
So if you please can recommend me someone/shop to offer a HPTuners mail in tunes I would really appreciate it

Thank you
