Bolt ons, fast intake, 438rwhp
Just figured I'd post up my results. 2000 camaro, m6, 9" 4.11s. Mods are, 231/235 custom grind cam, fast 102, 102tb, 42lb injectors, racetronix pump, 1 7/8 headers into tsp duals, underdrive pulley, 104mm lid, SD tune. It made 399.8 on a ten bolt with smaller headers, a homemade h pipe that had some terrible flow, and an ls6 intake, smaller lid, stock injectors and stock fuel pump. Changed the exhaust, intake, fuel, and rear, and it laid down 420/391 and then we messed with the tune for a final number of 438/406, on what I'm hearing is a reliable dyno.
