Went to a test and tune tonight at capitol raceway in crofton md., what a doo doo track + no nitrous again, something went wrong with tune and everytime I sprayed, the engine started shutting down cylinders? I've gotta get it figured out it worked great on the dyno! Anyway made three decent motor passes, best 12.10 @116. ( with 2 degrees timing pulled and 7%fuel added) 80 degrees outside, 150ft above sea level.
