I was out testing the new D&R HD prop shaft & was spooling it up A little when A challenge went past me at like 30 mph. I let off the brake & matted the gas & the challenger seen my light come up when I let off the brakes & he got on it. about 5 sec. later I just blew past him. on 93 octane 12-15 psi. ( 2-3 psi boost launch)..
