So, a 2013 Mustang GT puts down over 410 to the wheels stock? I thought they had 420 horse at the crank? There's only a loss of 10 horses through the drivetrain according to that dyno graph.
Shouldn't a stock Mustang GT have about 360-370 at the rear wheels stock? Something doesn't seem right to me. Maybe those two dyno runs are after being dyno tuned with the JLT and AED tune, with 414 HP and 390 TQ being the best numbers?

Yeah the numbers seem right post tune but no way pre-tune. Maybe those two runs were both post tune/intake runs back to back.

Yeah, that is why I was getting confused. Sounds more like it.

No I brought the car in on the stock intake and tune and did a run and then installed the JLT myself on the dyno, flashed the tune and did the second run. Not saying the numbers are accurate at all, because they dont make sense but it was a before and after lol

Stage_3

Ohhhhhhhhhhhh,.............you said "stock" Mustang GT.
A stock intake and tune is not stock.

MadMoose

No it was on the stock tune sorry. 100% stock. Thats what I meant by "stock intake and tune"

Stage_3

And you put down 410 horses to the wheels stock pull?

MadMoose

Yeah, like I said, I know thats not accurate for a stock car. Makes me have no faith in dyno numbers really. The gains showed up at the track though so I'm happy.

Stage_3

That's all that matters man!
How do you like the JLT cai?

Notice the sizeable increase in torque starting around 2600.

Yeah something ain't right there. Hmmm

We all know dynos aren't 100% accurate. But the track can't be too misleading.
