Well the fan and full tank are easy fixes....lol. I like the mph and times as they are consistent with my cars... I will end up running bracket I am sure. I had a Christmas party in Indy last week and there was a car show at the convention center next door. All racing vendors. NHRA reps were there at a booth as well. We talked awhile, but I don't feel like I got anywhere with them. They flat don't under stand anything foreign. I feel I could run a stock class. No internal engines mods, but the factory supercharger seems to be a problem for them. So, bracket racing is all that is left. Grudge night racing....lol.... Have you ran into any problems in class racing or have you just been testing and tuning...
