I had a 5C and Mike's tuning on my previous car (a 2011 GT), loved it, great combo. I'm currently shopping for another 2011/12 to do the same stuff to (sold the car, regretted it ever since).
My best 60' was a 1.59 with 255/50-16 M/T Drag Radials. 3.15 gears, offroad x-pipe, Boss manifold, Airaid CAI, Rousch tune, Circle D 5C. Best 1/4 ended up being an 11.41 at 119, 1.60 60', on 255/50-15 M/T DRs. That was with E85 fuel. My car didn't seem to care if I footbraked it as high as it would go or left off idle...it was always in the 1.60-1.64 range, depending on the DA that day.
