This has to be a first -custom tune disappointment

[ROtested]

The email came in yesterday advising that my custom tunes were ready, Woo Hoo! I returned the truck to stock and brought the programmer inside. The Pegasus software download proceeded without a hitch and the "targeted functions" optiooin loaded my 3 custom tunes into the Gryphon with no issues: Custom 87 Tow, Custom 87 Perf, Custom 93 Perf.

I have been running the canned level 2 since I got the Gryphon in June and have been very happy with it, to the point where I was surprised at the very noticeable imropvement(s) it made. I went back out to the truck, hooked up the Gryphon, loaded up the Custom 87 Perf tune (level 2) and went for a ride. Big disappointment. It felt like I was back in stock programming and the truck felt as though it had significantly less performance than the canned level 2 I was running. I am certain the custom tunes were loaded into the Gryphon correctly as they were listed on the unit properly during "power programming" and after loading in the new custom tune, the number 2 was displayed indicating that I was running the custom level 2 tune. I came back home, loaded in the level 1 Custom 87 Tow tune and while it shfted a little differently than the custom 87 Perf, it was also less than expected. The canned level 2 performed significatly better than both custom tunes I tried. I didn't try the Custom 93 Perf as I have a full tank of 87.

I am in no way second guessing my descision to purchase the Gryphon or implying that I am an unhappy customer. I am just surprised as everything I have read indicates that I should have felt just the opposite going from canned to custom. I plugged the Gryphon back in to the computer and ran a "calibration update" which removed the custom tunes and reverted the Gryphon back to the canned tunes. I hooked it back into the truck, loaded up the canned level 2 and the truck runs great, right back to where I was before.
