Also, we are going to have to go to the dual Cobra pump setup like Dennis because the fuel pressure is starting to drop at the upper rpms.The original tune had it pulsing the injectors more at upper RPMs, but that would only exasperate the low fuel pressure problem if we tried that. Ed tuned it safe but cautioned at the track under heavy use that we should run 100 octane unleaded fuel. Man, the trans shifts 100% better and now with the drag radials, it is not hitting the rev limiter between shifts. The superchips tuner software is sooooo versitile. This thing feels light as a feather. Hit it from a 40 roll and it will blister the tires. it ran 12.7's before the tune last year. I'm throwing out a guess by the butt-o-meter 12.4's is possible. March 6 it's going to Dinwiddie and try it out.
