Just recieved my Gryphon..Is this right?

XPerties - what Lars said is absolutely correct. Bill would have shipped an upgraded unit to you with the most recent firmware and your custom calibration already installed.

You can also check if your Gryphon has at least one custom tune installed, without taking it out of your truck. Use Diagnostics->Tech Support->Version Info and look at the "Calibration". It should look like "0.x.xxxx" where the last 4 x's are [usually] the same as the serial number, and should start with a "0" (zero). If it starts with a "1", you DO NOT have any custom tunes.

It looks to me like you programmed your truck properly, XPerties. I'm assuming your "custom tune" WAS in the Level 2 position? And yes, there may be a short time (about 50 miles of driving) before the PCM fully "learns" how to work with the new strategies. Still, I'd expect you to sense a difference right away, especially if you changed from the stock tune to your custom tune. Most of the improved "feel" though is only going to be seen under high demand, such as hard acceleration.
