Has anyone found real differences with their race fuel tunes? I suppose I would need to dyno and run qtr. miles at same day and conditions. but up to now all the effort I put into running race fuel fails to impress over running pump fuel at the track. First, it costs $90/5-gal of 101oct unleaded fuel. Then I run nearly all of the pump fuel out of the system. I add about one gallon of race fuel to mix with the remaining pump fuel, switch to race file and nearly run all of that out of the system. And finally, I add the remaining race fuel into the tank at the track when nearly empty, keep it in race mode and run no better than I do with Pump fuel and tune. It seems I am either doing something drastically wrong or I expect much more from my race tune than one should. Any dyno and/or 1/4 results would greatly help along with which tuner you used. My GIAC remap doesn't seem to have much of an improvement over pump ;| Should I give it more of an adjustment period? I seem to go through an awful lot of prep and pay$ for not much gain ;|
