"If you look at the dyno graphs, the F80 makes more power at every RPM than the E90. That means more power under the curve not just at peak rpm like the E90 does. Which means even at the same amount of horsepower, the F80 is faster."
Maybe be true for stock or bolt on E92; but that M4 is going to need new turbos to catch a charged E92. Than is it really worth the investment.
Charging my E92 was the best thing ever.
