I just installed a ported setup w/ a 2.76 upper and I want get it tuned one time instead of multiple so im considering a 100 wet plate kit or a 2/4lb lower. What kind of power gains does a ported setup see with a 2.76 and a lower? Im sure I can get into the mid 600s with the NO2 but if I can be near 550 with the pully combo only, I might do that. Also I have a Mafia and BAP, what else would be needed for a lower or NO2?
