what's in your area? and would you mind spending the extra money of the 93?

how much more is 93. And how much better will it make my car run? and yes i have 93 availible

no, i mean't spending an extra 10 cents per gallon on the 93 octane everytime you fill up.. the price in chips will be the same.. and your car will be slightly faster but nothing to go crazy over at all..

but since it is your first chip and all i would say just get the 91 chip and use it for a few months until you get used to it.. then with the money you save on gas you can upgrade to the 93 chip and see if you like it any better and decide from there..

but hey, that's just me

nah, just go straight to the 93. Paying and extra 1.50 a tank isn't bad at all.

if you have 91 and 93 octane gas available, get the 93, and run 93 octane gas...

if you only have 89 or 93octane gas (like me) get the 93 and run 93

if you only have 89 and 91, get the 91...

its that simple...

91 is for areas where that is the highest available octane, it's not meant to be a choice for cheap asses that don't want to buy "premium" grade gas

just wondering, what happens if i run 91 on a 93 chip?

01-31-2007, 07:41 PM
no harm, car is slower
