just stick with mixing race gas or meth injection

 

just use toulene, buy it at the paint store. 1 gallon per full tank. it should raise your 91 to around 93

 

the best way is to get a meth injection kit and raise the octane to like 100 run more timing and more boost that way.

 

bump

 

here is what the booster stuff does you have 91 + booster you have 91.3

only goes up .3 soo not worth a penny of y money

 

yes i think about 1 two 2 gallons will bring around 94 95 its not to much money either

 

okay then, I guess I'm going to go with the toulene.

 

Best way? How many daily driver Evo's have we seen with blown engines because of meth failing? Even with failsafes in place because they're not 100% and we all know it.

This guy is simply wanting to run the equivalent of 93 octane. I think the BEST way for him to do that is through toluene, like I suggested earlier in this thread.
