My car is tuned for 91 octane.
I currently live in a town with the highest of 90 octane.
What do I do? Octane booster? I have access to 108 octane but no 91!
Opinions would be appreciated.
Cheers
Cooper

 

I think that you should be fine with the 90.

 

No detonation no problems

 

Do you not have your handheld tuner to flash back to 87 or stock tune???

 

get a new tune... for 108... lol

 

if you were reeaaallllyyy worried about it you could fill up with .872 gallons of 108 octane and 14.828 gallons of 90 octane yielding 15.7 gallons of 91 octane. lol

 

Dude, you must be bored

 

+1
wow... did you learn that in highschool?

 

yeah it took all of 2 minutes

 

I have an SCT chip so yes I can put the stock tune on by flicking the switch...and have been, just wanted to be able to run around on my 91 tune.
Cheers for all responses
That 108 is around $8 a gallon!! Wow

Where in NM do you live? due to your higher elevation you can afford to run a little less octane than your tune specifies. For instance here in lubbock, tx. i can run a 93 tuned car on 91 just fine.

just my .02

 

I live in Clovis so 1 1/2 hours from you!
A few of my friends here in town run a lower grade then what their tune is set for, just wondering.
Subtle02gt, what do you know of Protech there in Lubbock?
Any experience?
Cheers

Oh sweet. Yeah i've got a few friends from clovis/portales as well

Rob's (the owner) a good guy. Does great worth with drivetrain. He installed my 4.10's and does work on alot of the local stangs.

 

Your 14.01, was that at Idahlou?
If so, how often do you go there?
Cooper
