Hey man sorry to keep bothering you about this tune I know your problaly busy but I have PM'd you several times, and gotten no response. I installed my tune tonight nd drive for about 30 miles. It still feels like stock but the shifting stinks. I had superchips before this tune and I was able to program it to how I like it firm shifts that felt heathy but not to much. with this tune it feels like the transmission is slipping and it hisates alot. Is there anything we can do I am thing about taking it out. It might do damage to my transmission. Please resond. Thanks Gene

 

Try to give it more time to learn.
After they programmed mine, it also felt stock until about after 100-200 miles. After that, I could definatly tell a difference.
After I got my 285 tires on I could barely spin them, now I can lit them up so easily.

 

yeah thats cool but when im driving and i hit it to go into overdrive it just doesnt move justs revese then finally about 5k itll go in to gear i have never had this problem before i installed this tune. what is the deal????????????????????

 

Well, that part I can't explain. Best to talk to Jason when you hear from him.

 

i just put my factory pmc in and it shifts find.
