445hp, thats it? my GT is putting down 555hp right now, and wheelies off the line once a perfect shift is reached. at one point i found the car doing wheelies through 1st, and 2nd gear. the car is amazing, and has tons of power. my GTO is putting down 548hp, and runs low 23's on bayview bridge in drag mode.
when do i get the unique upgrades? I just got the skyline, and then quit playing. All i wanted was the mustang. Do i have to beat the whole game to get them?
