My 2007 Silverado Build...again
#584
It's just a stock 5.3 with a little bitty turbo. It's not gonna be anything spectacular. Going to do some tuning on it today and see what happens. We've have guesses as high as 538. I'm going to say 475

Well slight change of plans lol Supposed to race a 10second grand national tonight. Putting on a 3bar map, hooked up the 2step and gonna crank up the boost and let it rip. Poor little motor lol
