Something's gotta be wrong here. My completely stock 6.0 except for Maximizer headers and JBA mufflers did almost 400 hp.

My luck with dyno's in Indiana will always produce a different result plus or minus 50WHP

All dynos read differently was you 400hp on a mustang dyno cause that would explain it I’ve seen cars move at least + or - 50 from different dynos same tune

Mustang dyno? No clue but this shop does anything and everything, including actual cop cars. I doubt they fudge the numbers.

I have seen shops inflate numbers just to draw naive customers.
Dyno's are tuning tools
HP and Torque numbers from the Dyno need to be verified at the track to be seriously considered.
All that bs said.
If Dyno is properly set up
Them are some nice numbers

Mustang is a brand of dyno that is know for reading high not saying they are fudging any numbers just differences in dyno my guy has dyno dynamics brand which is know for reading low which is great cause when someone asks for numbers your not lying but they sure get mad when your “slower” car blows there doors off

Either way it doesn't matter. Just posting for a reference for others and will see what it does on the track in April.

True. It's more the before and after that is a good indicator. I went from 357 to almost 400 HP so a healthy bump from the tuning itself. What was the initial HP?

I have no clue what stock wheel horsepower actually was. stock to the crank is 350HP then minus 15%. So I'd say about 297 to the wheels.
