Tim drove his M6 Blackwing in from North Carolina for the Blue Belt Performance Package. After installing Green high performance air filters, Gigs ported throttle body, Brisk silver racing spark plugs and Tapout resonated downpipes, we completed an oil and filter change. Then the car was moved over to the dynamometer bay we starting on the tuning. Peak power increased from 412 to 498 whp, with more power at every single point across the rpm range.
