At 7.99 gal. its not the most cost effective fuel out there. I have to say Its nice to treat the car to some 100 oct. race gas from time to time. Headed back to the drags on Friday so when i dump in 105oct I should get a better mix. Rather than 91oct mixed with 105oct. I wish it was like $5.99gal and more available I would have a new fuel map made and run 100oct all the time
Beware the dreaded "placebo effect" that occurs with some mods...
Kidding aside, this likely isn't doing much for you, but there's probably a slight benefit since you've tuned the ECU. Didn't you have a dyno-run with some race gas added, and it gave a modest gain?
