Race fuel
Hey, I have a 2015 auto z-51 corvette with a&a ti blower making 11.5 psi , 17/8 headers x pipe and meth injection. Also have the z06 fuel pump, on stock cam. The car made 671 ho and 616 tq. I was wondering if I could run a mixture of 93 octane and 110 race fuel and bump it on up to 700/ 640 ish with just the race fuel and new tune , and still have just 11.5 psi boost. I would use a handheld tuner to switch the tunes back and forth . Thanks for any input

Not sure how much you would gain by increasing the octane you're running, but you would need to ensure that your octane blends are consistent with what you tuned it at in order to avoid detonation. I would go flex fuel and you could easily make those numbers and never have to worry about the tune, if e85 is available near you.

OP here no way on driving 90 mins to get E85 so just turn it up if you think the stock block parts will take it.
