Hello,

I'm interested in purchasing a Corvette that has been heavily modified for road course/track use. The engine is LS3 based, 416ci with a 12.4:1 compression ratio and runs strictly off race gas, it puts out 800 hp. My question is if it would be possible to modify the tune to run off pump 91/93 gas without having to lower the compression ratio or change engine components? It is a deal breaker for me as race gas is $11 per gallon, and at $200 per tank, that makes the car too impractical for me. But if I can switch between tunes, for street (91/93 octane) and then track (98/100 octane), I could make that work. What are your thoughts and opinions? Thanks in advance!
