i am using a sort of home built kit for my n20 system. it's basically the nitrous works kit only using a NOS fogger instead of a plate.

im not sure the brand of the gas solonoid (the previous owner painted them black to conceal them!) but the fuel solonoid is a compucar, anyway....i was wondering the proper jetting combo for a 100 shot and a 125 shot.

i had it jetted at 47(g) and 53(f) at the track and only picked up 6mph in my trap. NOS said that this was the jetting for a 100 shot, but c'mon, 6MPH?!?!?

i only sprayed thru 2nd and 3rd though

ALSO....recently, when i spray, the fuel pressure gradually drops to almost 30PSI!! this worries me, please help.

btw: stock 91 LX 5.0.
stock fuel pump that whines......
