Julio, I just tried the car at the track with the daul nozzels. The car is a 10.70 128 car. I can't get the car to burn all the alky. I took fuel out of the chip and the reg. I started taking fuel out of the initial settings but don't want to go to far. I read where you said to turn the initial setting counter clock wise if the blue knob is on 1 or 2. The car went 11.30 at 123 surging with 25lbs of boost 0 knock. O2's were 800-810, how far can i go down with the initial setting. I really need your HELP. Thanks
