Loaded the predator extreme tune in 10 minutes. Very easy. Kept the edge hot juice on stock setting to see what the predator would do by itself. The first thing I noticed was the smoothness of my tranny shifting compared to the edge. With the edge on any setting I always have these surges and when I finally hit OD -- my turbo barks -- with the predator no surges and no bark. Seemed about the same smoke as the Edge set on Extreme 150 HP.

Tried the Edge on level three and the truck still shifted better and still no bark. Seemed somewhat quicker with this stack and a little more smoke than usual. Jumped to level 5 on Edge and didnt see a big change. I was dissapointed but then after about 20 minutes of driving the truck woke up like crazy . The accelaration and lowend are screaming, the topend was smooth - hit 1400egt at about 93 starting from a standstill. The smoke is ABSOLUTELY RIDICULOUS ! I actually felt bad for a couple cars behind me

I am pleased. Surges are gone, better shifting, more TQ on low end, faster on top and ABSOLUTELY RIDICULOUS smoke. And Im not a big fan of wasted fuel

As for the question - to the guys running this stack - are you seeing the same thing with your truck having to take about twenty minute to 'wake up'?
