I was making 504whp with the stock pulleys, stock supercharger unit, stock engine, 1000 ID, no fuel return, 255 pump, on 93 gasoline
Now I have 340lph pump on the way to use e85 with, and just did the 9lb pulley swap, and I don't know if it will net anything but I just put the GTR plugs in, I am hoping for 520whp with my next 93 gas tune and 550whp with a e85 tune!
