throttle linkage ??

went to the track today finally, I've had the engine together and running since 2002. after 2 passes at 12.6 at 106 mph, i realized as soon as i shift into 3rd it really just lays over.

doing some checking while there. noticed when i press the pedal to the floor I'm only opening the butterflies 3/4's of the way. i have the lokar linkage on the car. tried every different setting couldn't get anymore out of it. who makes a correct linkage for our cars. this is just the universal setup. what is everyone else running?
