I checked the gap on the new plugs they are still gapped at .035 ,,but the car just hit 80 k so ,feel the stock pump is losing flow in the upper ROMs,one member up here was running low 12s at like 111 or something and replace the fuel pump and picked up 4-5 mph.don't get me wrong the car is strong 40 mph roll I can break the tires loose without nitrous ,then again it could be the track with a faulty timing system.I am just going to give the car a good once over get put it on a dyno and go from there.Thanks for the input
