Alright I have a ls1 with a twin turbo im throwing at it, im going to run e85 so I know I need at least 85lb injectors, my issue lies with the stock setup, can I use the stock lines or should I go bigger? I got some 3/8th steel flex line but I don't want to shell out for the rest of I don't have to. My goal is 700-800 to the wheels, I assume line size wont cut it for this goal? any input would be awesome.
