stock 2012 5.0 manual

Ok, maybe for a datalog but there are thousands of people who tune their car with just a wideband in their car. Whatever I'm done.

I'm not confused about how to get the data, just making it clear that this wasn't a tuning session.

You going to dyno this one too?

I would probably do a before/after. Not really that concerned about it right now though. There are already a lot of dyno queen 5.0s that can't lay down what they've got, so I don't see a need for another one.

It is now, but that was with the original engine at 2500 miles. It gained about 2mph with the new engine, so I think there's a little more now. Cold be 400-405ish, maybe. Pretty good for a stock (reflashed from Ford) tune.

I would feel more confident tuning a '13. The pistons were significantly revised, and the tuners have become more sophisticated. I'll probably have mine tuned after the summer.

You going to dyno this one too? Maybe before doing the tune in the summer, see what it does, kind of interested to see the difference just between '12/'13

400rwhp is still plenty for her to get in trouble with, she doesnt need a tune, lol.

I didn't bring up the thread....you don't need to tap into your wideband harness either, it's right on your instrument cluster.

No, YOU have it on YOUR instrument cluster. I have a 2012. And unless you tap into the car's onboard sensor, the sensor data is not going to be on the graph.

Wow, way to bring up an old thread. Since this was just a "fun" dyno run and not being used to tune the car, there's no reason to tap into the wideband harness.

Why not use the wideband that's built into the car from the factory?

In all fairness his is a '12 with a brand new '13 motor in it

And there is a reason he's not tuning it, from the other thread he had about #8 giving up all while BONE STOCK. Really isnt a bad idea, just look, he got a free engine out of it, and had he had it tuned they would have blamed the tune. 390 is plenty to play with to not need 15-20 more hp to keep the warranty for a bit longer. Were doing the same thing with my wife's '13 GT.

This dyno was before the '13 motor.

So throw another ~8hp on top of that, not too shabby! lol

Didnt even notice is was a OLD bump....

This dyno was before the '13 motor.

The flowchart that Danny posted seems to throw a finger to the Magnuson-Moss Act.

[BMCSean]

Ahh yes the GP, never rest!

stock gt's do 390?

[YALE]

Afr gauges are notoriously unaccurate. There was a good article written by Bosch engineers that explained... I'll have to dig it up.

Reading Plugs and listening by ear are the only way to go.

If its the stock factory tune, don't even think about sweating it.

Is that really what you want to go with?

[majorownage]

I guess Ford's stock tune is all sorts of wrong then...

[VaderTT]

Damn, I was going to say.

In before Majorownage give bad advice!
