My 95 m3 with chip and 7,200 rpm redline hits an indicated 165mph (guessing since the speedo only goes to 160) in top gear.
Also, speedos are always generous with their speeds.. its to help people who choose to ignore what size tire they SHOULD have on their car and sometimes go wider, taller, etc and changes the actual speed of the vehicle. So if the car is supposed to have 225/45/17's and you put 245/45/17's on there, that 5-10mph that you'll gain by having higher sidewalls offsets the factory discrepency.
