I'm going to kansas this weekend. Gas north of the Tx/Ok border is 91. My tune is for 93. I really dont have the time to go out and make a new map since I get to see my parents once a year. Can anyone help or should I just back the timing?

 

eh. just take it easy and you'll be fine. if it really bugs you (or if you want to drive that hard), dump a gallon of toluene or xylene in with each fillup. will easily get you past 93 octane. either is available at most paint stores.

 

cool thanks. i'll watch the datalogger and add if necessary.

 

turn down the boost
