Hey I know most of you guys probly own an edge evolution programmer. How much more mpg do you get with it?
Also, most of yall call it a gryphon. What is the difference because i have never heard of that before?

 

The Gryphon is the same hardware as the Edge but has the ability to be custom tuned by www.powerhungryperformance.com. The custom tunes are much better than the canned tunes.

Do some reading in the Tuning forum and do some searches on mpg with the Edge.

 

my mpg did not improve... however it is winter and very cold / winter blend of gas, along with the much better driving characteristics.... it made it 100x more fun to drive and my foot wont keep off the skinny pedal.
