Not making power on nitrous

Spraying 150ish? dry. Hits like a mad man on the initial hit then falls flat. On this pass, I spun out of the hole, got planted and hit it. Let off for 1-2 switch, hit it again in 2 but it didn't pull hard. Let out middle of 2, hit it again in 3 and had nearly nothing there. Ended up going 11.6@119 with a 1.81 60'. Previous pass on motor went 11.80@112 with a 1.55 60'. Pass starts 2 mins into the log. 12.0ish AFR most of the way down and going fat up top. Any ideas?

Don't have any filters in the fittings, nor a stand alone filter either. I'll take it all apart and look for any debris.

Sounds like all fuel and no N2O... test it and see if it sprays...

Still could be a fuel only issue - not all dry setups spray the MAF to add the fuel... in fact, the better ones don't...

Don't have HPtuners on this laptop, so I couldn't see the log... but 15.5* and no nitrous will be a dog as well... for whatever reason, doesn't sound like its spraying...

OP - Do you have a fuel pressure safety switch?
