The off idle launches are wierd. I noticed when I stab the gasthere is a slight delay and I mean slight (left on 3rd yellow)and poof off it goes. Possible the brake pedal still hanging up. Possible I have a carb issue when I do a full throttle stab, Need to figure that out. I also noticed from watching the videos a slight amount of black exhaust, so I'll definitely be messing with the carb for the next time and bring the jet kit with me.
