What's up guys, first post in this most awesome forum.. I just bought a 2004 mach 1 , great body, perfect interior, and the last owner saw fit to remove the mach motor and install a 2003 supercharged svt cobra engine..runs well, idles great, but goes major lean with boost. Figuring no tune on the factory mach ecm. Question is, should I just go with a cobra Q ecm made for the supercharger. Or would an aftermarket alternative be appropriate? New to the 4.6, but have a semi built 94 cobra convertible to help share the garage. I know the systems are night and day different, so any advice appreciated..
