A converter and a good tune and could be in the low 14's I reckon, 13.5?...I doubt it, that needs 266fwhp, can a true 50hp be gained if the tune is off some?...depends how wrong it is now, it don't sound that bad with that mph, its just the 60...even that 15.02 should be in the high 2.0's.

with 3.91's and same hp you'd be>
