I have an o2 firehawk m6, I am very close to ordering the NOS kit for ls1's. I am only going to run an 80 shot, just wondering if i will need a bigger fuel system and need to adjust my timing?? I herd on a basically stock motor i can use stock timing? My mods are slp long tubes, cat back, mass air& bellow, slp ram air kit, and t/body spacer..Please give thoughts on nos kit and questions.. Thanks,,

 

as far as i know there is no 80 shot
you do not need to upgrade your fuel system until you remain under 100 and may be 150 shot
