Charlie re-tuned my 04 Yukon Denali after i ran a 15.1 on a 89 tune! All i can say is Holy ****! Today i drove it hard for a while and when i would turn a corner and get straight i nailed and the truck fell on it's nose! It was the traction control kicking in! I have never felt that ever! It was breaking all four wheels loose! This truck seems night and day from the bad *** 89tune! Charlie is the man again!!!! Thanks again Charlie! Couldn't be happier again! I'll keep you posted! The best part is it has been in the 70's this week in Chicago and it feels this strong, can't wait for the cool weather!!!!!!!!!!!!!!!

 

maybe in water?

 

Sorry, It's been dry here for 3 days and sunny! I don't need to bs here i have my 11 sec GTO to bs about!

 

Good deal,now go break in the 14's with that SUV
Thanks again and call soon

 

My wifes SUV has surprised many people! Thanks again Charlie! It sure is fun to drive, moves out pretty good for 6000lbs!

 

15.1 with only a tune is awesome.Not many get that
