Racechip 60-130

In hot weather, heat soak can drop performance. I would expect power output to drop after a couple of runs.

You two may be both correct. Also, whats crazy is I got my fastest dragy time on map 5(put octane booster for first time) instead of map 7. It leads me to believe that higher octane has to be used to for the more aggressive tune. I'm going to try again tonight after putting octane booster.

My best Racechip run was using Map 6 instead of 7(because of wheel spin slowing down 0-60) with octane booster. Map 7 is best used on roll races. I have 21 in rims too with brand new Michelin 4S and fully stock Competition besides the RC.
