You must have a freak engine.. When I had just a tune/muffler/intake my 5.3 made 280whp. Now I have headers and im right at 300whp NA on a nitrous tune... My friend has an 08 5.3 with open stock Y pipe and 100 shot it made 360whp/415wtq, NA it made 270/280.. Just curious to why yours made the numbers it did. Seems kinda high, but hey anything is possible lol

Thanks! next mods I want to do are gears front and back with a 9.5 14 bolt rear end conversion and true trac. A Circle D built 6l80 then get a complete 6.2, swap it out with the 5.3 and put a front mount turbo on it. With those mods I think I will be happy, should be a pretty stout daily driver.
