ive looked for a better needle is there anywhere that sells needles by them selves? all i have been able to find is whole kits.[/b]
Call LRD Performance (Just Google LRDPerformance, not sure the rules on posting Links and Phone Numbers) and tell them to ship you a EMP needle and clip. After I experimented with several different jetting configurations I found that for me the NCVQ needle was just to lean. It didn't ever perform crisp and seemed to be the cause of the infamous bog.

See my post here for my jetting specs. Hope this helps.
