I hooked up a Zex kit the other night before I went to the track. I set it up for the 125 shot and I ended up running a 12.7 @109. The problem is my previous best N/A was a 12.9 @ 107. I pulled the system last night to check all the connections and it all seems in order: no leaks, the right fuel and nitrous jets, and it is activating at wot. I don't have a bottle heater or pressure gauge yet so I'm not sure of the pressure it was running at. Track temp was 135* with high humidity and the barometer was really high too. I'm running autolite 3924's and the gap was .050 ( I forgot to change them to .040). My N/A run was in much better conditions but I still think I should be getting quite a bit more out of it with the nitrous. I'm going to pick up a pressure gauge for sure soon and hopefully a bottle heater. Anybody have any ideas on what could be the problem?

FWIW I'm running Edel. 6032 heads, TFS Stage 1 cam, ported Cobra intake, 70mm tb, 76mm maf w/ 24 lb inj., 190 lph fp, Kirban fpr, msd 6AL, elec. fan and assorted other bolt ons.
