Great job Livernois, you guys nailed it!

3 questions:
1) How much more gain is there on 93 octane vs. 91? 91 is readily available most anywhere, but sometimes you have to look for 93. I would assume this is an issue of diminishing gains, but am not certain.
2) If you get a 93 tune, but can only find 91, must you alter your driving habits or will your tune still back off the timing to prevent detonation, thereby rendering it safe?
3) Ford techs can tell when the vehicle has been flashed or tuned even when the stock programing is returned I assume by some sort of counter. Can they differentiate between a performance tune and a software adjustment that only affected a speedo calibration after they have been removed and returned to stock? I would assume that setting it back to factory would also remove an codes that might record excess torque, etc...?
Thanks!

I feel bad to say this but I'm unaware of the differences between the 2015 mustang 5.0 and 2015 F-150 5.0 other than the exhaust manifolds. Do you have a complete list of changes? You can PM me if you want so we don't get off topic too much.
I do agree that they run better on premium, but I'm trying to run through my options.

You can always run higher octane than your tune is set up for, but you should never do it the other way around. Yes we leave safeties in place, but they aren't designed to allow for a constant mismatch in fuel. Its sort of like skydiving and planning to pull the emergency chute first.
While the counter doesn't tell them what was flashed, they also have q database of when Ford updated the flash. If its been flashed 5 times, and Ford only recorded 3 of those, they'll know. Trust us, just be honest. We know it goes against years of trickery that other tuners have engrained into this market, but times have changed. OEM's have been burned too much by poor tunes, and people pulling warranty fraud, so they closed the doors. If people continue, they'll do what chrysler did and lock us all out. So please,just be honest. There are a ton of cool dealerships out there.

No MAF, Why? Is this on all the new engines? Perhaps they figure they can save costs because the widebands, this is how newer EFI conversions work so perhaps is isn't that bad. It would eliminate the issues with surging with blowers because the MAF readings fluctuating with the by-pass valve changes.
Is tuning without a MAF easier for you guys?

Ford says the truck has 10.5 vs 11.0 for the mustang like before, but I can't find out if the cams are different again. If the cams are the same this time that would be great for tuning with headers.

As for the tuning. Speed density is the same to tune, if you are used to tuning these the correct way in the first place. If you are doing a "dirty" tune and bandaiding things, then MAF is easier. But if you understand the operation of the ECM and engine, and how they interact, then it's no easier, or more difficult than MAF.

I just put the tune in my 15 EB and what a difference!! I tried both the 87 tune and the 91 tune and WOW is all I can say, also nice job on fixing the low speed shifting. Great job overall Livernois!

We're exctatic that everyone is appreciative of the time and effort we spent on this. We knew that this would be well received based on the amount of complaints people had on the stock shifting and throttle.
