91 Octane on 93 Tune?

I really want the 93 Octane Tune on my 2014 Mustang V6 but they only sell 91 Octane here in Phoenix, Arizona.

What would happen if i run the 93 Octane Tune while pumping 91 Octane Gas?

Current Mods are
- Roush CAI
- Roush Axlebacks

The key thing is understanding the difference in the tunes. A 93 tune is pushed harder than 91 because the higher octane fuel can take it. If you try running a more aggressive tune on gas that isnt up to snuff you will damage your engine.

Yes only put 91 in if your car is tuned for 91

Yes. Running a higher octane tune with lower-octane gas can cause engine knocking/pinging which will damage the engine

Yes, the reason it's called a 93 octane tune, is because the engine parameters are set specifically to work with 93 octane fuel. As stated above, it can cause damage to your engine if you run lower octane on a higher tune. If 91 is the highest in your area, stick with the 91 tune.

But on the bright side, you can run 93 octane on an 87 tune safely lol. In all seriousness listen to these guys. I raced a slow maro a couple weeks back and I had the 93 tune on 87 octane. After the race I was getting gas and the car was barely turning over, also it felt like I was driving a 1997 civic. I started freaking out and my check engine light came on a few minutes later and my AFR was at 10.00 and it usually idles around 14 or 15 so I immediately cut the car off and installed the 87 tune and after the car got readjusted it finally started running normal and the check engine light went off. I will tell you this though, that was one of the scariest moments of my life.

Just because you buy it stock doesn't mean it was always stock

Not 100% but you can take certain steps to make sure. For example look at exhaust bolts for signs of being recently replaced, if you buy off a forum see what the guys posts look like. Now at to be 100% sure but there are things you can do that may provide signs that the car was recently put back to stock.

you could use a good octane booster but that could get expensive but cheaper than rebuilding your engine from running the wrong gas. You can use a higher octane than tune calls for but never less

You driving cross country and they don't have 93 octane at any of the local stations that you want to fuel up at.

I think he was asking why he would race on 87 octane with a 93 octane tune.

Even then that is something you should plan for.

why would you want a tune that you can't get gas for? I understand if you were concerned about traveling but get it for what you can get at the local gas station.

I'm thinking this was already asked but I gotta ask myself.

Exactly. In Florida, I had a 93 tune, and an 87 tune for when I went on road trips. It came in handy on my way up here to Alaska. North Texas and Colorado had 89 at the highest. Here in Alaska, 90 is our Premium octane.

I think has many many times Mud. People just don't use the search button or know how.

OP, another thing you can do is get tour car dataloged. Do a search on my name and you will see that I say this over and over and OVER on many different threads. A datalog with take what you have in to more detail and allow for even great refinement of the tune to to make the best of all the mods you curently have. I moved out from So. Cal to Boston a year and a half ago. They only have 91 in CA buy Boston had 93. I went from a canned 91 Bama tune and had them send me a 93 tune. Immediately after loading the tune I felt nothing. No difference in how it normally felt. However after going through 3 rounds of datalogs the car was completely different from what it used to drive like. Rather than obsess about the bugger number in the octane a tune is set for get your 91 tune dataloged. You will like it so much better.
