I have a 2000 GMC sierra with a 5.3 V8. I have a Diablosport Predator Stage II. I run somewhere around 15.5 in the 1/4. I have not ran at a track but i plan too soon. I am trying to find more ways to speed up and get a little more power. Let me know if yall know anything.

 

rich i knew something was up when you first said that it ran 14.5 in a 1/4,cause it sounded unreal.

 

SORRY!! that is 15.5.. not 14.5.. my mistake.
