Powderlite turbo Nytro fuel pressure?

[TOPGUN]

I know I've asked Dave this before but can't remember. I'm thinkin 40-45. I was running the sled today to put on the trailer and it was running like a bag of chit. I pulled the plugs and the sled is running EXTREMLY rich. Put it all back together then notice the fuel pressure is around 48. I'm hopin this is all that is wrong. It hasn't run in awhile since it's first few startups.

Set fuel pressure at idle warmed up and you can fine tune it and see how A/F gauge is showing.
It will be crisp and clean and easy to tune once running.
Turn key on for about 48 lbs and once running adjust to get good idle and should be around 43 to 45..

But would the sled running pig rich be due to the 48 pounds at idle or should I be looking for something else?

43 running at idle warmed up. I had mine at 48 and it would load up on the bottom at idle. If you need more fuel pressure you will need to adjust your RB3 map on the bottom.

Man I hope your right. I'm already second guessing myself on install........LOL,
Thinking something came unplugged ..son on so forth.

Well, put new plugs in, turned fuel pressure down , got it running but man it is running like crap. Did notice that the fuel pressure was really fluctuating up and down, weird. Tomorrow I guess I'll back track everything again, unplug the rapid bike and plug in the factory stuff and see how it runs. This thing is rich, but why all of a sudden. It's been running off and on for two months with no issues.One other thing, almost like it does have a timing problem when starting.

I wonder , if the fuel pressure is fluctuating if either a vacum hose has come off or if the map sensor or regulator is screwed up. Why else would it run rich?
Another night of diagnosis.

look at the map senser mine screwed up and it was running rich but at idle it was ok so that is a little diff from your problem i still would look at the map sensor it may be broken
