Edge evo dash mount programer
On my Evo CS shift firmness 1-2 +15%, 2-3 +12%, 3-4 +5% in "tow mode" or power level 2. Nothing else is changed except for tire size/gear changes. The 1-2 shift definitely makes that infamous 5.4 wot sqeek stand out lol
When mine is on stage 3 with the custom tune I got in it I can kick from a stop sign while I'm turning lol and get it to spin sideways with my 35s all I have done to my truck is a k&n air intake and a street performance throttle body spacer and the edge evo.
