D’Angelo drove down from Michigan to have our Purple Belt Performance Package and Mace Stage 1 cams installed. All the fuel system upgrades weren’t in his budget, so we were limited to E47 fuel. On pump gas the car put down 545 whp and 588 wtq with SAE correction. Then on E47 he made 612 whp and 610 wtq (SAE corrected), or 624 whp and 621 wtq (STD corrected). His fully automatic flex fuel tune automatically detects alcohol content and will switch on the fly from 545 to 612 whp.
