Couple of questions? Is yours a DBW or cable driven TB. Also, most of your changes were dramatically different from the 1999 Radix truck in the depository...IFR, Octane tables, predicted air lfow, etc. The Spark ECT tables and modifiers were way off the stock radix tune.

Your might want to start with that tune and then make some small changes if needed. If yours is a DBW, then scale the injectors according to the redhotsupra sticky. The 1999 is for the return system.

Stock file is very good... or at least that is what callaway uses on their magnachargers tunes.
