When I had installed the boosters with the umbrella, it was very rich and I had to take a ton of jet out. I had a head gasket problem and had to shut it down before I got to where the car fell off. It did level off at some point and did not seem to respond much after that point, but I was trying to make the car pop or lay over or something to be sure I was lean. It never did. Unfortunatly, the head gasket was letting water in the cylinder that I was reading EGT off of, so that was not accurate. The final numbers showed the boosters slowed the car down and after the head gasket was replaced, I put the carb back to original and it ran 10.20's again. The car does not lay over at high rpm or miss at all.
