This is just a short review for the ones on the fence about getting a Gryphon, and the benafits of custom tunes. The "Canned" Gryphon is a big improvement over stock, most of the time I ran level 2, but did try level 3 for 2 tanks, level 2 seemed to be more of a low end improvement and level 3 more on the top. MPG improved about .5 MPG, with this 10% bleanded gas, but it does recover quicker, from putting your foot in it. Thursday I loaded my custom tunes, I got a 87 preformance and an 87 tow, I progamed it to proformance, and that is what I got, WOW! The truck has super responce, and power all the way threw the RPM range. It feels powerful, The difference in the custom tunes vs the canned is the difference between canned and stock. My only issue is now my wife wants one for her Expy. Thank you Bill and Corey for all you hard work, your great product, and your great customer relations.
