It seems with the 5.0 tuning #'s are all over the place. This goes for stock #'s and tuned #'s. With this car already tuned to run on premium the #'s we are seeing are to confusing. Since almost everyone is running this car on premium shops should be going from 93 stock to 93 tuned.
I think so far the only shop that has done things right and has realistic #'s with tune and CAI is AM Bama/Rose team.

 

Ive always liked Doug. He was a straight shooter (Even if notoriously behind) when he was in 'bama. He even left my mail order tune completely unlocked so I could play with the timing and fuel at full throttle. In the end I ended up with it set back to his conservative 29.0 degrees and 13.0 AFR (E10). 19/28 mpg and 12.9 @ 107 on a soft 2.01 60' is pretty decent for a 2007 with just CAI/Tune.

PS If that doesnt count because of the mineshaft air the one in my sig isnt.

 

Yeah, it seems as if there are a lot of "dishonest" claims... I actually spoke with Jay Tucker (JLT) and we both agreed that most of the claims are not going to happen.

But with that being said, sometimes the car is delivered with 87, or with 3.31's (making a 4th gear pull mandatory).

For me, these were my gains. Both on 93. Seems like an honest gain

 

Who tuned your car?

 

Mine is a simple SCT email based tune...

My tuner (Performance Dyno) says datalogging is very limited, so customizing the tune was not possible

 

Also you have to take into consideration the difference between autos and manuals.

The AM/Bama Car that made 363 rwhp Stock, 379 rwhp tuned, and 385 rwhp CAI/Tune was an Automatic. I do like the fact that they didnt change fuel between baseline and tunes. Their numbers are in line with what I would expect without manipulated fuel octane, intake heat soak, oil and water temps (Which can add up to 20-30 rwhp) to make big numbers.

 

Dont forget using SAE/STD correction...

STD my car puts down something like 396 or something close to that

 

I have an auto so these #'s look good to me. The only dilemma is if the CAI is worth the money for 6 rwhp.

 

That was a prototype (which means some design changes may be coming) and they may still be working getting smooth non-turbulent air past the sensor. In theory their is a 7% loss in flow (Ford Numbers) because of the factory air intake. Assuming the engine can use it if you get half that with an aftermarket air intake you would be looking at 14+ rwhp, I suspect we may be up against the fact that the factory airbox may already be feeding close to what the intake manifold can use, The inlet tube and air box on the 530 bhp Boss 302R1 look an awful lot like the factory 5.0 assembly (although they could be larger 2012 Boss Prototypes) from what I can tell without actual measurements. If it can feed the 8300 rpm intake manifold on that engine it tells me their may not be huge gains to be had.
