I went to the local dyno to compare to see which tune was better on the dyno. I was using a dynojet dyno all pulls were on 87 octane two pulls per tune with a 20 min cool down between reflashing tunes. my truck is a 2013 with 1400 miles and 3.55 gears I did 4th gear pulls and shutting it down at 5000 rpm at around 115mph. runs 6 and 7 are the 5 star runs 8 and 9 are the stock tune runs and last are 10 and 11 which are the SCT 87 Canned tunes. also my truck has a afe 4 inch catback and airaid intake for all of these pulls. and it looks like 5 star won by anout 15 hp and 10 ft lbs pf torque. just felt like putting this info out there an independent review enjoy! sorry about the small picks just zoom in aanf you can see them better.
