I have a 2012 Mustang GT automatic with 3.73 gears, boss intake, accufab 84.5 throttle body, steeda cai, magnaflow competition catback, and JDM 93 tune. My Dyno numbers are 405 HP and 401 TQ. Do you think thoses are good with these mods?

Was that on a Dynojet dyno or Mustang dyno? I seen auto's put down 400 with intake, tune and off road x pipe. So I guess that's around right.

Dynojet at JDM Engineering in Freehold, NJ.

Do autos normally dyno with that close of Hp/Tq ratings?

Even still...you figure with the Boss intake manifold, the numbers would be even more spread apart.

I know it's off topic a little bit, but I'd be interested to know why.

Dyno is only a tool to measure and compare from one modification to another. You cant just throw a bunch of mods and dyno because you will never really know exactly what those mods are good for. Doesn't matter if is dynojet or loaded rollers such as mustang and DD. The final number will be high or low depending on the condition, weather station, setup, etc... Most peooles think dynojet just automatically put out high numbers and mustang put out low numbers but this is far from the truth as mustang and DD could easily be calibrated to compensate for whatever scenario. You should always have a number to compare with using STD or SAE correction factors to get the best result.

A graph showing the power curve would be more useful then just peak numbers.

Agreed, seems actually high for me. Was anyone else there you can compare to? Trap speed is what I like to see for power. Dyno is just for fun or from one mod to the next.

I can give you my numbers off of my pull with my set up. I have a 2011 5.0 Auto, with stock gears, CAI, Boss Intake Manifold, Longtube Headers, off road h-pipe, magnaflow catback comp. exhaust, and Bama 93 race tune and I pulled 410hp on a mustang dyno on the dynojet I pulled 440HP and my HP was still climbing going into 6800RPM. Mustang dynos always post lower given they take into account different parameters. Your numbers sound right given the addons you posted.

I take it you didn't do a baseline run w/o mods.
