Well the stock Mach 1 with the A10 and H-pipe put down 405rwhp and 368tq it was a little less than I thought but I can never say enough great things bout the people at Steeda. They treat everyone great and are like family. Thanks again to Matt, Chris, Jamie, Scott and Julia

Uhh, why did they stop the pull at 6300rpm? The engine power peaks at 73-7400 with the GT350 manifold.

Pull that thing to redline and you'll see another 15-20rwhp.

Looks right in line with a Bullitt. Seems like Ford didn't adjust the lowr powerband any. Even at around 3000 RPM it looks inline with Tuning By James' Bullitt dyno video for Steeda on the same dyno.

Looks like thy DID tweak it around 5250-6000 RPM through the Bullitt has a little bit of a dip there right where the TQ and HP cross, and then takes a little to recover. So, it seems they may have tweaked and smoothed out the top end.
Blue is stock.

Maybe due to the intake manifold change on the Mach 1.

This is 15% loss to rear wheels, makes no sense.
My 15 Dino’d at 407hp with a Steeda tune and intake
This is pathetic and I’m trading mine in tomorrow!

Ha!
The MT-82s only lose about 11%, I’m sure the Tremec is similar, and they’re absolutely right, the dyno ended way too early. I expect the car to put down ~420-435 at the wheels stock and properly corrected, just like the Bullitt.

BTW just for an opinion that nobody asked for, the Mach I is the best looking s550 bar none. I’ve always thought the front end of the 15-17 looks like a little too much like a mouth-breather, the 18+ a little too much like a weasel with an overbite. The Mach 1 front end just looks bad ass.

Can you talk about the stock limiter? Is that set for breakin and off after first 1000 miles or how?

I think the speed limiter on the Mach is at 166 but could be mistaken.

Think its 163 for the base, 166 for the HP, which is odd. Not sure why 3MPH matter. I also have not heard about the PPL2 having a different limiter than the GT or PPL1 but it should have more stability than the Bullitt which is 163 limited.

The whole limiter thing is an odd scam. We know a Bullitt can do over 170MPH. The Mach1 base, HP and GT PPL2 likely can all do the same.

I need to get my non HP Mach 1 to go 170MPH. What must I do to achieve this?
