it's a 3.0 L, not 3.5. with a chip and exhaust, you're at close to 400hp, and probably over 400 ft-lbs.
I agree with ABTSportsline here. The E46 M3 was a NA 3.3 L engine with 333hp. This engine is only slightly smaller, but with TWO turbos and putting out LESS hp. From the factory it should already have at least 400hp, no modifying necessary regardless of if you care about warranty.
