OMG 27* of timing??? WOW! Definitely change your rev limiter to spark instead of fuel cut. MAF calibration, smooth your PE, and max out your enrichment rate below the PE table.

No idea why that happened. Looking at a Maggie tune though, the max fail should be at 16,000HZ not 1,600. And the voltage test should be enabled and set to 1 Mil under DTC. I'd leave this tune alone and just change what everyone has recommended on this. It's a good starting point so far. The two little mistakes above even I missed. Looks like someone knew exactly what they were doing, but it was like 3 in the morning when they were doing it. Hence the simple mistakes. Been there, done that.
