2012 Mustang 5.0 Dyno Tuned - Boss 302 Intake

[TunedByNishan]

Final results from this 2012 Mustang GT 5.0L I calibrated over the weekend.

429 HP / 381 Ft-Lbs SAE (437/388 uncorrected) and holding power beautifully to 7700 RPM.

The red plot is a baseline run which consists of a slightly modified stock tune file (stock ignition timing, stock cam timing, fueling, etc.) vs. the blue finalized tune file plot.

Modifications include:

JLT Performance Big MAF Intake, American Racing Headers Long Tubes, Catted X-Pipe, Magnaflow Cat-Back Exhaust, and a Boss 302 Intake Manifold. The car also has a T-56 Magnum XL Transmission with a 3.73 Final Drive.

Calibrated on 93 octane fuel with HP Tuners

Thanks Eric & the whole HPT team for making the best tuning solution for the Coyote!

Looks like you had some TQ mgmt issues with the stock tune. Did you use the same CAI for both pulls?

[SultanHassanMasTuning]

nice curve!

Feel free to share your cam timing(that you spent your own time and money to find lol)

No TQ MGMT issues on the stock file. I modified the stock file with that in mind. The baseline run, however, had all stock calibration data in terms of performance.

After altering camshaft timing, the dip in TQ was pretty much remedied.

nice curve!

Thanks!

I am not this productive when using SCT haha!

HP Tuners is really an amazing calibration tool for Ford PCM's

Sure! I will post up some charts when I get some time later.

It didn't take much to find the right camshaft phasing for this setup. A few dyno runs at most.

[AKDMB]

Wow, thanks man. It's nice to get some data to work off of when your tuning cam timing on the street.

I completely agree.

To be quite honest, tuning cam timing on the street would be very difficult.

I have learned that these engines are very sensitive to cam timing being right. Only a few degrees can increase torque by 10-15 ft-lbs where it is needed.

I honestly wouldn't know how I would dial in cam timing on the street with an NA setup other than start with a known good setup and probably leave it at that. You really need the dyno to show you how things have changed.

It's a bit easier with a Turbo car because oftne you'll see increased spool time when you increase dynamic compression through VCT.

definitely something going on with the 'stock' tune at 4400 to 5600 rpm

you should have made a clean pull so you can really see the difference

it looks like on the bottom end below 3300 rpm the stock tune has more torque

I did more than 1 baseline pull. It showed the same dip in torque each time.

Fuel was right at 0.82 Lambda and no KR. Was very clean.

My first changes were to intake cam timing only and it immediately picked up as seen in the blue plot.

I'm for more info on cam adjustments

[kris5597]

I'd recommend cam angle bracketing. Lock exhaust cam at 0, then lock intake cam in each position and do each pull. Takes more time but worth finding hidden torque. 50* to 10*, then retard exhaust in 5 degree increments from there to see where torque rises. Works really well.

Hmmmm....the only time I have seen the sharp drops like shown with the stock tune is when TQ mgmt is taking over.

[SultanHassanMasTuning]

yes like torque source 1

[AKDMB]

bump for the cam timing too lol

Although it was a stock tune file, I made some modifications such as TQ MGMT, etc.

Between that and datalogging, I know TQ MGMT was not kicking in.

I don't have nearly as much experience tuning coyotes as most in this thread, but this much I am sure of.

I just saw the post i was wondering why the stock intake lost so much power in the midrange that is kinda odd do you have datalogs for each run?

All things equal it shouldn't. It will always have more TQ in the middle than the Boss or CJ.

Whats the gain with headers/ intake/ tuned???

[Deuce]

Sharing is caring for us novice. I am on a self install exploration on a 2011 A6 lol. I managed to tune my boss for install, but am finding it hard to tune everything for much else My eyes went crossed at this point.

[etm351]

back in 2011 or 2012 i had a car 2011 5.0l that was stock with a custom tune and swapped out a boss intake, I ran that car for 2 or 3 days, i was unable to get an significant power up top just 2-4 rwhp. But at the time we were still trying to get cam angles right and didn't have good info as to what the camshaft angles were doing, that could hiave been the reason and the fact it was stock exhaust. Haven't been able to do it with a car with long tubes which would have to help out with the boss intake.
