Taking It To The Track

for your next step, you should concentrate on your mph at the other end of the track. re-read reply number 20 where it is suggested to look at the fuel pressure gauge at high mph wot for a fuel delivery problem. you could have a look at it on the streets (highway) . if it is good, which i think it would be, judging by the blue pump (and 1/2 in. lines ), you could try richening-up the 3310 on the secondary side. mine was running lean at wot, so i drilled the plate in the back. i could feel the difference. if you decide to try drilling it, first measure to what size you are at now. you would have to select a drill bit precise to the thousanth of an inch.
