Removing speed limiter

[Sheetmetalfab]

Removing the speed limiter and raising the rev limiter with the PV3 is super easy. Both the DynoJet and HMF tunes have it already done to them.

I calculated RPM vs Speed a while back to calculate IGR stuff. The following is in 6th gear...

28" tires go 783 feet per 1000 rpm. So, 9000 rpm = 7047 fpm X 60 minutes = 422,820 fph / 5280 = ~80 mph @ 9000 RPM
30" tires will go ~85.7 MPH
32" tires will go ~91.5 MPH assuming you have the power to turn 32's to redline in 6th gear.

I have the dynojet tune on my X4 and can confirm 60 mph on gps with 30% geardown portals at the rev limiter. (Set at 9200 rpm)
31” system 3 tires. (30.6” diameter)

I like high range as is but could still use 10-15% lower low range when fully loaded crawling tundra.
