so with that cut off of 150+ mph, how long does it take to get there. At about what speed do you shift out of 3rd, and can you hit 150 in 4th?

There is no way to hit 150 mph in 4th gear. Also, I think the car is gear limited to 155mph or so.

Theres not much power above 6000 RPM for a stock motor anyway. A tuner can reset the rev limiter higher just in case you don't shift in time, at least the engine won't shut down. Try to shift between 5500 and 5700 RPM as that seems to work well. The speed limiter is another issue and can bedisabled also with a tuner.

by "tuner" what exactly do you guys mean? for my passt i used to have the tuner was something you could download into your laptop then get a cable that went from usb to obdII and do the changes from there is there something similar for our cars?

laptop tuners are so 90s man! now they have hand held tuners, like the diablo and SCT are two good ones, that hook up straight from the car port into the cable that goes to the hand held tuner where you can change all kindsa fun stuff, but u can still connect the tuner to a computer to download various tunes, like a maximum torque tune or a 93 octane tune. electronics are FUN[&:]
