At Winternationals one year, I was given a set free to use. Went back after some runs to complain that I slowed down. The Holley rep changed heat ranges and I tried them again, with same results. The Holley rep took me over to the Autolight rep and he gave me a set. Installed them and was happy to be back in the fold. I never again tried them.
