if i read your post right your fuel log is regulating the out ports of your fuel log and then you have another regulator to your Nos fuel...
if this is the case..this is BIG,BIG No-No...you do not supopose to regulate a line that is already regulated....this spells disaster.
You need your Nos fuel side fed straight from the fuel pump regualted one time..or take off the fuel log and run a regualtor that has a free flowing port...run the fuel lines to your motor and regulate off main regualtor..run the Nos fuel supply from FREE FLOW port to its own regualtor and test flow the Nos fuel from that Independent regulator. Holley silver regualtors are a popular choice of regualtors for dedicated Nos fuel feeds
bottom line regulate your Nos fuel 1 time
i hope that made sense ... :roll: ..lol
