raced a new z4 M coupe last night on the highway. This was my first run with any car in my new speed3. we went from 80 punch twice and i would get about a car ahead and hold it steady until 120 when we would shut it down. Needless to say I was very impressed with my speed3. my mods are modded air box, test pipe and TXS boost controller. his car looked stock. The new M coupes have 333hp and 260tq and run 13.5-13.7 in the qt mile at 103-104 mph. (drinks)
