True Street Dyno Tune
 

The guys at True Street were able to squeeze out a little more HP and a pretty large chunk of Torque on my Mach 1. Keep in mind the Mach is N/A:

Still having some stalling issues but hopefully I'll be able to make it back over to McKinney in the next couple weeks to see if it can get sorted out! Then it'll be time for a full Maximum Motorsports front suspension install...

Good power for a NA 4.6!

Nice tq gain.

Real good power for an Na mach. What's done to the motor?

Awesome man! Those are solid numbers!

Well according to the previous owner:

Forged pistons/rods/crank - stroked to 5.0
Stage 3 MMR Heads
Comp 106200 Cams - all associated components upgraded
Ported stock length intake
JLT RAI
MAC Long Tube Headers
Mezierre Electric Water Pump
Upgraded oil pump/gears (forgot exactly what brand)
ATI Super Damper
Catted X-pipe
Steeda Catback
4.10 gears in an IRS

-that's about all I can remember

We're thinking the compression ratio is 9:1 or less. This is what HPP says they remember building it to (in 2008 - trying to remember in 2013 doesn't make it 100% certain) and the guys at TS say that's likely the CR they went with since the previous owner was planning for a twin turbo setup.

Definitely liking the torque gain they were able to get me, just hoping we can get the stalling issue worked out. Sucks when you slam on the brakes in auto-x and the car stalls out mid-turn (as I experienced at the Mustangs v Camaros event).

Lower compression motors (especially modular motors) respond very well to aggressive timing curves. Any idea what the lower rpm timing numbers are?

I honestly have no idea.

Stellar power from a, possibly low compression, NA 4.6.

Why do u guys keep saying good power from a 4.6 when he clearly said its a 5.0? Lmfao

Ok its a stroked 4.6, there happy lol.

I was referring to it being a 4.6 based motor.

Thanks, we're still working on getting the stalling issue fixed. Have all brand new Motorcraft TPS, IAC, O2 sensors and then EGR delete plate and vacuum lines capped and brand new NGK TR55 plugs gapped to .054" but the car is still stalling at dead stop sometimes. Hopefully one more trip to adjust some of the parameters can finally get this rat bastard sorted out

Correct. Would be sweet if it made sense to put a coyote in it!

Dang pretty good numbers from a former 4.6. I want to say my buddy's Mach put down something like 36x with full bolt ons and a HPP tune. I have always loved the 03-04 Mach 1s. It actually inspired me to get into Mustangs. Made me buy my first Mustang an 01 GT back 8ish years ago now.
