LS2 Motor Swap into Rice Burner
 

I'm dropping a complete 2005 GTO LS2 motor and 6 speed into my Mazda. Build date of the donor GTO is Dec of 2004. I need to be able to disable most of the self diagnostic tests. I have the GTO's motor, headlight and dashboard wiring harnesses with both computers. Is Speartech my only option or can I use the GTO's PCM with ??? tuner software?
