i run s-trim at 10-12lbs, track heat heads, track heat intake and comp cams 284HR blower grind cam.Jon89 said:Thanks for the reply Kieth. What would be a good "off the shelf" cam to run with an S-trim and Track Heat heads? My exhaust is 1 5/8 long tubes with off road pipe and flowmaster cat back. I plan on going with a 70 mm t/b and 80 mm mass air. Would I still need an fmu with 36 or 42lb injectors? As you can tell I don't know much about it.
