The have told me directly the tunes are made for Michigan.
Not sure what to believe but mine runs like complete shit in Florida.

Nice runs....

I did good too on a street tire and a passenger

Nice times. But everyone else seems to hate their Roush tune

I love mine. Wouldn't even think of changing tunes. Car got 24.4 mpg and runs those times I can't see paying over 1k for a tune to pick up 1-2 mph and voiding the warranty. This car is amazing 44k out the door and I daily drive it.

My Roush stage 2 only made 560HP and only 485 TRQ. Numbers should of been higher. So I say Roush tune sucks.

Been very happy with mine but I have the Ford Racing kit which is a different Tune than Roush. No drag slips but my car did 587/476 on installers Dynojet. Speed limits are my only complaint as the car gains MPH so fast I can only enjoy it a few seconds at a time...........

I feel ya. Mine put down 527/410 be that as it may it runs 10s at nearly 130. Dumps are a tool. Numbers mean little the drag strip mph is the real indicator of hp.

Damn nice numbers. I was watching the American Muscle trying to time their giveaway supercharged 850+ hp mustang at the drag strip on youtube. It is a manual but with all that power they couldn't go below 11's and above 125 mph. It is a whipple charged car as well if i remember right!

Every at the track said it's a 727 hp package. I had the dyno graph with me they couldn't believe it. 0n a da of 3200 plus it went 11.27 @ 125.44 da yesterday was 386. I raced my buddy's whipple charger it went 11.74 at 124. He was on a street tire.

Sounds believable if 4WD and the 6.2 engine.....seems those are rated at 420/460 factory stock and 4WD to launch.

Car and Driver tested one at 5.4 0-60 and 14.1 1/4 mile........
That engine is almost enough to sway toward a GM truck.......almost...:headbonk:

That was there calibration. One of our customers ran his 2015 manual, 3.75" pulley, he went 10.4, 136mph.

There cal issues are well publicized. Drag strip does not correlate to daily driving, torque codes, varying power, etc.
