The problem is that 110 is so high your timing would be past MBT (mean best timing, or maximum brake torque). Going past MBT will yield less hp. With a 93 octane tune you are probably real close to MBT already.pay the 75 bucks and get the tune for it and get some more HP...thats just my opinion
big +1 on that one...wouldnt it also foul plugs on a stock setup?Not only is it a waste of money without adding more timing, it will also ruin your O2 sensors in short order. 110 octane is super high and for people with 25+psi, 250+ shots of juice, 13:1 compression, etc.
