Just put in 108 octain booster from advance auto and filled up with 93 , not the racing fuel but octain booster and set my 93 on Sct ! It's running like a beast !

Its feels stronger than just using 93 gas and I was having some ping . Not anymore hehe

Just wanted to share !

 

Wonder what that will do for mpg..if anything.

I put a bottle in my Yota occassionally but I am on the highway a lot. I use it to help clean injectors more than anything else and eliminate occasional ping. Too expensive for minimal improvement to do every tank.

 

Usally I net 20 miles less to a tank with the 93 tune but I love running the 93 tune for when people wanna give my truck a run
It also souls diffrent I like it but my pocket doesn't !
