Just got back from Korea and tested out my Edge
 

Evo that was converted to gryphon with 2 custom tunes a year ago. i haven't had a good chance yet to really get on the accelerator(been raining a flood) but i have noticed that i don't see much difference at all between the 87 performance and 87 tow custom tunes it seems when accelerating. Ok, so i've edited my post since i've been able to get on the accelerator today and man what difference. I basically just adjusted the shift to my liking but everything else seems spot on. i also like that the torque converter is locking in 3rd in the tow tune....i'm not sure it did that prior to the custom tune. very pleased, gas mileage seems pretty good too. this badboy gets to 70 in a hurry!!
