Hey guys just to fill you in its a stock lt1 with just a couple extras... 3inch duals with borla mufflers(stock manifolds), Full K&N Cold Air Intake, 10.2 wires and NGK Iridium Plugs, MSD Opti, and thats about it... Ive heard ppl talking about a 150 Shot.. I dont know anything about NOS atm.. I just know I wanna kill LS1's...I know it can be bad for an engine but I've done some research and gonna give it a shot.. Just wondering if someone has a setup there using they would recomend.. Thanks!!
