I'm going FI in a few weeks and am worried about having to shift into 5th to get 130+ mph as my car is a 3.73 car.
3.31's, 275/60-15, 7K redline and 4th got me 135 at the finish line. It bumped the limiter in 4th before crossing the line. I think the online calculator I used showed 133 mph with my setup at redline but I dunno if it compensated for tire growth (if there is any at this speed)
