OK guys, im really serious about buying the Superchips Custom Tuner 9100, aka SCT 9100. This uses the same files, as the SCT chip, but just reflashs the PCM instead of chipping it. Troyer peformance has it for 425, i can get it other places, but im going with troyer performance (They r an f150online Vendor). Also u can buy the $75 software and cable, so u can reflash the tuner if u add other mods and need a special tune for it (02 maf, PI Intake, cams, etc.), Via email. When u order it online, u can list what mods u have, what year ur car is, what the EEC catch code is, my is LJC1. Any special suggestions, etc. Anyway, How much of a difference does using the tuner and 02 MAF make for hp? Costs for the 02 maf assembly (Airbox and intake tube)?
