I'm not Lars, but, I'll try to do as well as he would have.
First, make sure you are running the latest version of Pegasus. Mine is V2.01.0127 and it's up to date. If yours is any earlier, it's definitely out of date. If out of date, use the Pegasus Update Manager to get the latest version. DO NOT try to update a Gryphon with an old version of Pegasus!
Next, set your tune back to Level 0 on your truck and remove the Gryphon. Bring it to your PC and start Pegasus, then, plug the Gryphon in to a USB port.
The Gryphon screen should light up (I think mine becomes red?) and you should see your unit's Serial Number (S/N) on the status line in Pegasus. Click on Updates->Gryphon Update Manager.
If there is a firmware update, go ahead and install it. DO NOT install a calibration update. That will wipe out your custom tunes.
Now, once everything is finished, go back to your truck, turn the key ON and plug the Gryphon back in. You should be able to reprogram your truck to the desired level now.
I calculated an unloaded circumference of 2741 for your tires - what you calculated. Using 7% rubber squish (which is close to 3% total squish), I get 2644 as the figure you should enter. This is MUCH larger than the value you were using. Try it. Remember to hit <Enter> to save the new value and then scroll to <Done> to start the programming.
If this still doesn't work, something IS wrong with your unit and Bill will have to be the one to help you.
