Originally posted by smokeator I have seen these on ebay and I am new to this so do these work or do they just mess up your car? If they do work do you get the h/p gains they state?
From what I know they dont work, right now there is only one ECU mod and that is from Technosquare, and even then you're talking about maybe 5hp without any other mods? Try a few of the bolt ons that are available (Plenum, Cats, Exhaust) Then look into the ECU mod.
Originally posted by Import-Tooner If anything, they will just lean out your fuel curve. Which will make your car maybe a little faster. Then blow it up.
