The tire size is completely dependent on inflation pressures, speeds, and manufacturer tolerances. We can usually get close given a tire size, but there will almost always be a need to correct it once the Gryphon is installed in the vehicle.

As Cody said, there are factors that will cause errors. Your plan to check things as they are is sound. If you find there is an error, go ahead and reload your tune with YOUR TS value and DO remember to check and adjust the GR too, if necessary.
You did good to load the tune first without opening Custom Options. - Jack |

I have another question for you guys. I searched for the answer before bugging you with it but had no immediate success.
Would it be okay to tow on an 87 perf tune if all I am towing is about 1700lbs? I don't see why not personally, especially considering most of the land I'm traveling is flat except for the last hour of driving (mountains). Overall, I like the way my 87 perf tune runs better than my canned 87 tow tune. If you remember the shifting issues I was posting about before, I never made any manual changes to the tow tune programming. These issues are gone with the performance tune. I'm just wondering if I can tow with my perf tune considering the very low amount of weight I am towing. It's a small pop-up camper. Gross weight is around 1600 lbs before loaded. Thanks in advance for your help. |

The performance tunes are rated for up to 2,000 so you should be good. But if you notice things like the engine and trans getting hot or the truck is searching for gears more often it probably wouldn't be a bad idea to switch to the tow. But you probably wont have any trouble on flat land if you drive nice.

Agree with Longshot - you really should not have any trouble at all. I doubt if even the mountain driving is going to be much of a factor in your case. Anytime you drive on mountain roads and the engine has to rev higher due to using lower gears, the transmission is going to heat up. I climb Mt. Graham (about an hour of driving and an 8,000 ft elevation gain) in 2nd gear all the way. Because of the speeds on that twisty, narrow road, I doubt if I'd be in a higher gear even if I wasn't towing, and the TFT would still probably get above 200.
