I love my truck. The only complaint I have is how it shifts. My buddy has an SS Silverado, which shouldn't be but maybe a tenth or two faster stock, and he runs 14.6-14.7 (although he has it reprogrammed, cat back, Volant CAI). Very impressive! Even stock he ran 15.6 his first time. I now have a cat back and Volant intake on and will be running sometime soon. I'll post my times. By the way, its a regular cab 4x4.
