Okay guys problem fixed! the purge hole wasn't fully tightend and it was loosing pressure! with all that done, I went out on a test run and WOW! I was running a 50hp shot and it really brought back memories of my srt days. I'm going to try the 75hp tomorrow.

Paul I'm curious what jets did you use? the book I have tells me to use 41 nitrous and 22 fuel sound about right to you?
