91 is like 20 cents more here, but no one around here sells anything higher at the pumps.

The 92 I got was pure gas (no ethanol) and like a dollar more

The 100 octane was 8 something

Luckily my buddy put it on his card so I lucked out on 10 gallons. Haha

I've never run anything, but thought it would be fun and was curious on what you all have fun

The 100 or 116 I get is unleaded and I pump straight into the car. The dragstrip has 116 in the 5 gallon jugs also but way too expensive. The 100 is $6.50 a gallon.

Did you notice any gains. Worse mileage?

Lol. True

Anyone dyno with race gas with our tunes? Does it actually help?

As Che implied, a tune for normal pump gas (IPD is tuned for 93 afaik) won't get much benefit from higher octane. If you tune for it, you'll definitely be able to get more power out :P

Your car will run it fine, performance gains probably no so much unless you run it several tanks and even then only in closed loop. Your mileage will go down for sure however.

Which part didn't you understand?

Well I added the 5 gallons if 92, and 100.

Instantly I noticed that it didn't ping at lower rpm boost.....then I went and got 17 gallons of sunoco 104.

It just seems to run smoother. Although I do notice that it's fading to 13-14:(. It did this before though. I hitting 17 tops...def pulls pretty hard. Smells like a jet. Haha.

Something is wrong with your car if you ping at low rpm with a 16t and are fading at 13psi.
