Cant find 93 octane around this part of Kansas, just 91. I bought a gallon of tuolene but am a bit scared to use the stuff on a new car with only 1500 miles. I am a little worried about warranty problems etc. Sooo I bought a bottle of Nos Racing Formula (I know octane boosters dont do much, but I read this is at least decent stuff.(?) and I installed the "93 performance tune with firm shifting" from my Diablosport Predator tuner. The car is running extremely well. If I bring the RPMs up --not powerbraking--before launching (automatic) It will do a wicked (one wheel) burnout. If I just take off hard it really pushes you back in the seat hard & picks up real nice. So I'm happy with the tuner & this particular tune in other words. My question is will this combo of 91 gas with the nos brand booster be ok with the 93 tune? Should I use tuolene instead? I would like to keep the added boost but dont want to destroy a new car or anything. Thanks in advance for any info-----
