True. BTW the GT goes about 32mph tops. Removing the restrictor just gives you more power, power as in more acceleration making it appear faster but the most you'd gain is a good 35-36mph. Still a good truck and fast out of the box. OS .12CVR is all you need for racing unless you track is huge. Then you'd want a faster side exhaust engine like the newer Fantoms, Wasp.12SE, RB C12, or Novarossi CX12.
