New PB 10.58 @ 126.33 100 shot 
Ran a new personal best in my 94 Mustang with a 5.3L swap. I'm still working through the tune with the Holley HP but with a pretty weak 60 foot I'm happy with the results so far on a 100 shot. Best on motor only was 11.40 @ 117.88 at near 100' DA. The above pass was done at 1100'. I tried hitting it with 150 but trans slipped so I aborted the pass.

It was low on fluid. It was rebuilt by a friend but the rear seal/bushing was never replaced and started to leak on me. I replaced and lost about a quarter of fluid and forgot to top it back off.

Actually it's on the trailer right now just waiting to leave work and hope my head cold doesn't get any worse.
Since the 10.58 I rewired the trigger for the nitrous and now it comes on when I release the transbrake button, before it was triggering by RPM so there was a slight delay. Last Friday on my first pass I had a 1.43 60 foot coming out on 100 but had bottle pressure issues and we got some rain so I never got a full pass.

Looks like I'm having a nitrous solenoid issue and not a bottle pressure issue. I made one pass last night had a 1.37 60ft on the 150 shot but just before the 330 it started dying off and started loading up with fuel. Bottle pressure was 900 at start of run at 850 at end. Datalog shows the Holley starting to pull fuel just before the 330 and has pulled 90% fuel by 1/8 mile to keep it at 12:1 A/F. So the fuel solenoid is working but the nitrous solenoid is locking up or dying after a few seconds. At the 330' mark it was .22 faster than my 10.58 pass.

IIRC you are running an nx kit? Call them and tell them your problem, a local buddy just finished his 6.0 coupe and had issues with his kit as well, they told him they had a bad batch and are currently sending him an upgraded kit as replacement

I had tons of problems trying to progress the nitrous on my sbc chevy 2, so I ditched it for the current lsx mustang project. Just spray the whole load outta the gate....you're only going 150, right?

It's jetted for a 200 but was using the progressive to limit it to 75% (150 shot). The above video was coming out on 150 but with the solenoids pulsing the nitrous solenoid started to fail. I've since rejetted it for 150 and switched it over to a non-progressive setting so hopefully without it having to pulse the solenoids they will stay open the entire run. I'll try it tomorrow night.
If that doesn't resolve it I'll be buying new solenoids.

Like most tracks it varies. On test and tune nights it depends on the sportsman racers, too many imports and street tired cars and it goes away fast. On slower nights with more combo/drag radial and slick tired cars and it's pretty good. Overall it's better now than it ever was before they rebuilt the track a few years ago. They just had some NHRA Funny cars/top fuel cars here last week so the left lane was working really good.
