The guys I trust see 8-10whp. I have been tuning since 2014 and I don't honestly believe there is that kind of power to be gained either. These engines come aggressively timed from the factory...they are not rich and the intake, exhaust flow really well (enough to support 500bhp easy).

You can make a dyno read anything. Make the stock pull heat soaked, then make the "tune only 93" pull cold, and voila...there is your big gain.

Spot on as usual my friend.

I am sure the dyno operators know how long to wait to minimize heat soak after and before each pull. I have been seeing so many standard corrected dynos on dyno jets. Even some reputable tuners do that. I would like to see SAE corrected and preferably on a mustang dyno. The delta before and even after tune can change when you are comparing STD to SAE corrected results as well. Anyways, thanks for the input guys!

I already did.

What does the k and n look like at the maf? Are there airflow straighteners like the oem?

I will post pics when I get home for you.

Got it done and dyno'd, 427.9 whp accounting for the average drivetrain loss from all online sources (14.29%) 499.3 crank hp, wheel toque is 424.9 so 495.7 ft lb

[vince3]

Any idea of what kind of dyno that is? Who did the tune?

[RedHotSS17]

It says online, dual eddy current AWD (all-wheel drive) dyno

Is this on pump gas 93 or 91 octane? What was the baseline on the same dyno before the headers? STD or SAE corrected?

The peak is my concern, but dynos are different. Peak hp at 5278 seems off. I wonder if that is just how the dyno is set up, or the K&N's smaller tube is hurting peak.
