I posted this in the dynoflash section but no answers so im posting it here. Ok i have a custom road tune by Al for 93 oct at Texas elevation. Tomorrow im driving home to colorado so Al provided me with a 91 oct tune for colorado elevation. When should i swap the tunes? And also there is one place in texas where i have to fill up and the highest octane the sell is 89. is this going to be a problem to run a 91 tune with 89 for a hundred miles or so tell i can top it off with 91? or should i find some of that octane boost and add that? sorry for posting in 2 sections but im packing everything up tonight
thanks

 

do you have a mbc? if so... turn down the boost few pounds if you plan on flying home...


if your just cruising then you dont need to adjust it... just let it be

cheers!

 

ya i was just going to turn it down to 20 or so. i usuallyl travel between 80-90mph on this trip becuase it takes all day. and at that speed boost will come on very quickly
