Done - procrastinated until about 830 (just so cold after working outside all week) called the ford store and they said bring it in we will help. They let me pull it in the 80 deg shop and just start working on it, the tech's loaned me tools and when they got free they helped me hand in hand to install all / CAI, SPARK PLUGS, T-STAT AND CATBACKS / done by one. Now that's a huge favor. Went home slapped the 91 tune on and went for test run. All I know is it burns rubber, now I'm looking for someone to race. I only did about a 15 min run and been sleeping sense (long week and long day)
Thanks a bunch. I'll keep you all updated as I feel it out some more

Dang man, that's Great!  You really have a nice bunch of guys there.  I'm gonna have to visit my Ford Store more often.  Glad you are happy with the results! 

Incredible service... Restores my faith in people!

I'm envious.  Enjoy!

Already itching to try the 4+ tune, i email livernois and asked if i will be ok seems how the pumps here say 92 min oct rating. the replie said probably be safer to stick with the 91 stage 4 , but the 4+ tunes do work much better. "work much better" that didnt help telling me that. Not sure exactly who responded to my email, I'll give them a call tomorrow. Also someone mentioned using octane booster, not sure i want to have to make sure i do that every time i get gas. Any thoughts?

note: my wife is the one who gets to drive the car most of the time. She's like "what did you do to the car, it realy go's and shifs so nice".  Maybe i dont want to put in the 4+

Anthony probably emailed you.  There is only one octane booster that has gotten good reviews here and right now, I can't think of the name. Great that your wife likes it! 

as I recall stage 3 on the 2013 is equivelant to stage 4 on the previous years Probably a stage 3 91 or a stage 3 93.

I can't even remember what mine is I think I have the stage 3 93 in lol

If I connect the tuner to my computer will it show what tune it says ?

what's weird is I can run 89 and it runs the same ? I wonder if the colder temps outside keep it from detonating w/o the higher octane. I've only tried it in smalle amounts of fuel if I know I have a qucik / short highway trip to make.

IIRC, there is only two tunes for the 13-14.  91 octane and 93 octane.  They figured everyone was just using the top tune.  There are 7 different versions out there.  You could see whats on the MyCal by preparing to tune the car and see what choices you have.  I would never dare to use 89 octane (or even 91 with a 93 tune).  It might feel the same driving around and nailing it a little but if you wind up to high RPMs through the gears you could do major damage.

pretty sure I have the V793 in which I guess is the highest performing tune they have out now for my 13. I know it's not recommended but I can't tell any difference in using different fuels. Funny thing I don't give the car enough credit for being a lot faster than it feels because its so smooth. The car I mean. I still need to look at my OEM plugs....I get some hesitation but never any detonation. The V7 update seemed like the shift points were better but the car felt a tad less powerfull too. I wonder if it uses less timing ? I assume the amount of tiiming is the difference in the 91 and 93 tunes right ?

Yeah, with the V7/93 you are Most likely in the 12's.  That's fast.  And smooth.  LOL  They probably did have to back the tune down a bit.  Probably timing or maybe a little richer up higher.

How many people are running 92 octane in a 93 tune? Sounds like you can but if the risk is to high I guess I won't. Is there any options for me?

Octane booster? doesn't sound sure fire, I'm getting mix reviews on it

Meth injection? Don't now much about it rite now but sounds like an option to safely run 93 tune (spendy option though)

The pumps do say 92 min octane rating, so does that (min) mean might be closer to 93 octane?
I can find 92 oct ethinol free fuel throughout Oregon, wonder if that would work?

One last thing I was thinking, could livernois custom tune for me so I could get a 4+ style tune that would carry boost out but keep timing of 91 tune?

carrying the boost to redline will have to wait for the XV1 tune for the 2013 SHO's. Then I'm sure a 91 and 93 will be available. I'd say get the 93 tune and run 92 and if you plan to beat on the car use some octane booster. If you know what detonation sounds like just be sure you never beat on it if you hear that sound.

If LMS is offering a 91 and a 93 octane, I'm pretty sure they could customize a 92 tune... If you ask nicely ; )

This may sound like a dumb question, but here goes anyway.
If he put a tune in for 93 octane and he can only find 91 or 92, if you just drove it normally until you could fill the tank again, wouldnt the cars computer adjust?
Thats what the knock sensors are for. Or because you put a tune in the car, are the knock sensors over ridden ?

Im ONLY talking about one tank full of the lower octane

If you are driving normally on 1-2 octane lower it shouldn't make a difference. When I was finding the best spark advance setting for my SCT tune I would program it +1 degree global spark over the previous setting then go do a few 0-60's while watching spark advance and VCT PIDs. When the spark was too advanced the car would knock (not audibly) and you could watch the spark advance instantly drop down to 0 then slowly climb back up again as a knock sensor response.

Best to stay at the octane your tune is rated for but if you keep the rpm low enough it should be ok.

Thats what I was thinking. If you dirve it normal through one tank of a 1-2 lower octane, you should be fine until you can rrun the higher octane.
The cars computer should compensate
