Just installed ATLAS 80
 

I got my FICM tuner today and installed the atlas 80. :woot: What a huge difference. I was stock before, no ECM/TCM tuning. My truck has an AFE intake and 5" exhaust, EGR delete, and head studs. and it made a huge difference. I am going to drive for a while on the 80 then maybe try the Herc.

Big Thanks to PHP!
