Depends on the dyno numbers and where they peak. Posted in another thread:
Maybe no one uses the 10% rule anymore.
Use this:
Maximum Speed = (rpm X 60) ÷ (Gear Ratio X Tire Revolutions Per Mile)
10% Rule = 10% more RPM through traps and adjust with tire size or raise the rev limiter.
If you are pulling hard through the lights - too little gear. If you are shifting at 1188 ft to 1320 ft, too much gear.
