Any benefit from using 91/93 pump gas at track events?
The engine is a stock S5 n/a with;
custom fabricated CAI
CorkSport header, high flow main cat and cat back exhaust
Pineapple Racing 6PI sleeves inserts
stock heat range spark plugs
stock ECU and stock fuel/spark mapping
OMP is still hooked up
I pre-mix @ 1/4oz/Gal on the street and 1/2oz/Gal at the track events
I was just wondering if it would be of any benefit to use 91/93 pump gas at the track events vs. the 87 pump gas that I use for daily driving?
TIA

with stock fuel, not really, if you lean it out its not a bad idea, the stock timing map is a little aggressive, it can knock in the midrange
