read scooters post and the subsection dealing with chips and the shortcomings.
I have heard much more bad about any of the popular chip makers like hypertech, jet, etc. No free lunch they waste gas, comfuse the computer and cause all sorts of trouble codes. Superstockers mopar perf ECM sounds like a baragain ! do that. be sure to read scooters entire post. He does fuel systems for a living (i think he does about 95 % sure thats what he does he is a smart dude and an engineer so thats good enough
) so he knows his stuff, and if thats not his exact job he is right, my old man has been doing fuel system for ford and DCX since the late 80s. He told me the same stuff scooter did.
