The mods on the engine don't really matter. The PROM is programmed with the base timing set at 6* BTDC and makes its timing "adjustments" based on this. If you set your base timing to other than 6* you'll skew your timing tables.

Yes really. The only RIGHT way to adjust the timing on these cars is to make the changes in the programming and burn a chip.
