when It gets hot, try a gallon of Toluene with a half tank
It makes a pretty big difference up here in Colorado with pump gas being 91
octane plus 10% ethanol. When I run 1 gallon of toluene with 8-10 gallons
of 91, the car is much smoother, much stronger, turbo spools up quicker,
feels much faster off the line.
Only draw back was a little more cranking time to start (maybe my
imagination) and made for $$ tank of gas.
