I have the same problem in my FED with a pro brake. I was told that pro brakes react around .4 and bracket brakes around .5 which would be perfect for me since I am about -.105 at the first sight of third yellow.
This may sound stupid, but heard of Alan Johnson doing it to get around the rev limiters in top fuel when they came out. He ran an extensive amount of wire to lengthen out the time it took to travel from the rev limiter to the ignition. I have thought of taking a 25' coil of wire and splicing it between the button and the trans brake/two step. Any electrical guys thing that would work. Could you use lengths of wire to tune your reactions times. I don't believe it is against the rules. :roll:
