I feel like I've asked this, but how do I get it closer? It's about 15 mph off at 70. It shows 85. And before you ask, I changed gears to a 4.10, and it was 5 off before the swap.
Check out the Dakota digital sgi-5 I need one of these too because I know have a supra motor a d trans in my truck and it's off by about 20kmh
