After much troubleshooting (due to some wiring issues) I finally got the Nitrous working on the weekend. I am running a small 100dry shot and was actually not that impressed... yes it pulls hard but I guess I was expecting more. I am thinking it could be running lean...?

The reason I say this is because I am already at 400RWHP and I had to bypass the FPSS (set at 38psi) to get the nitrous to activate. I am going to get her on a dyno to check the A/F and hook up a fuel pressure gauge.

What is your opinion? Am I running out of fuel?

 

If you still have a stock pump, then yes I do beleive you are running out of fuel. Stock pump is good till ~450ish I beleive.

 

Could be fueling, but I also don't think 100 shot feels very impressive regardless. You'd probably be a lot happier with 125-150 shot.

 

Yup, with the 100 it just feels like you get through the gears a little faster then norm with a little extra pull. I bet you still got a big grin on your face from it though.

 

A wet shot you might be ok, but dry is pushing it I think.
