hey guys... im going fi (centri) somewhere in the future but im on a budget. i was wondering if i can go ahead and do some of the upgrades now as money permits. can i go ahead and upgrade the maf (was thinking 90mm lightning) now and install it, before i get injectors? cuz im not sure what supercharger route im going in and dont want to waste money on wrong size injectors. i have an sct x-cal 2 by the way. also, is it ok to upgrade the fuel pump with a basically stock set-up? thanks.......
