i got a 2000 gmc sierra and allen done me a tune and before i had a granatelli. the granatelli felt better so i told allen and he asked what it needed and he sent out another tune and it kills that diablosport. dont let anybody tell you not to order one cause i live in georgia and i love mine

 

when im gettin the money ill be gettin a tune by allen, it will be worth a drive to his place, mainly since i live in san antonio heh
