OK, that's not so weird. I think Bill has input a TS value in your custom tunes. But, you did not say "which" speedo is "reading fast". If the dash speedo is showing 58 when you're actually at 55, you are very close to being "dead on". The dash speedo is normally going to read 3% fast when the odometer is giving accurate mileage. But, if the Gryphon speedo is 3 mph fast, then he has the TS value set too high.

Trouble is, you can't figure out what value he used. If you want to try to correct things again, start with a TS value of 2573 and make sure your GR is 4.10. Make adjustments from that TS value.

It was the Gryphon digital speedo vs my GPS digital Speedo. I know that the dash analog speedo reads fast no matter what. I'll try adjusting the TS through the custom menu again and hope it works this time.

Didn't work... Had the TS read 2574 and the speedo was back to being 9% slow. I guess I'll email Bill and see what he says.
