I took my truck to the track Saturday. I couldn't stay long so only made 3 passes, but had fun while I was there. I've got 54,000 miles on my truck, I've been running a "tune" (re-flash) in it for about a year now. It has tons of TQ which makes it real fun to drive on the street. Real happy with my results, I'm just a tick off a high 12 second 1/4 mile. I think with a little practice and couple of adjustments I can get there. I think I may have hurt some feelings in my 3 runs. Not bad for a heavyweight crew cab pickup!
