I was just messing with you Steve...I agree on the throttle body. A flex sensor and E tune would be a lot better than any other single mod for these cars. Ethanol right now is 2.40 a gallon in my area vs 4.29 for 93 octane. 50-60whp gain repeatedly vs cranking up the boost on 93 octane and making decent power for 1 pull before it drops 35whp on the next pull. Unless it's winter you can't keep the MAT low enough on a stock blower with pulley combination to keep it from knocking or pulling timing due to manifold temps on pump fuel. With E you can maintain full commanded timing with manifold temps another 40-50 degrees higher.

Agree, so why don't we do this to my car? (I know the answer involves a larger pump or two, and injectors)
