I was thinking about the S-AFC...so let me see if I get this right...The S-AFC is the only tool as far as piggy back goes that will allow my injectors to open a little longer? Does this include adding more air too? If thats the case, would that be the same as reprogramming the ECU, except I can control it? With the mods I have so far, anyone have any input on what else I can do or get to help get some little more horse? I want to get everything before I DYNO tune it. Any guess on what WHP I might get? I was thinking about a throttle body. I dont want to mill the head either or port and polish...its just too costy. I appreciate everyones opinion...thanks
