Think its easely true mine has a catless exaust, intake, pulley, tune and weighs 200pounds less than standard and I pull a V10 M5(standard) 6-7 carlengths up to end of third going to 4th and it doesnt catch up When mine was standard a V10 would annialate me espesially from 3rd gear it would going to 4th pull me by 6-7 maybe more carlengths and keep pulling away and you just give up
