How slow is my car?

This did come across my mind. What's the best method to check for leaks? Just test the charge piping, or the whole system from the compressor on?

18psi with 11-12* timing on 110 octane is your main issue.
Bring the timing up to 16-18* where it should be and I guarantee it picks up big time.
I also wouldn't be pulling any timing on 110 octane as IAT rises at your current IAT's.
Give it 1-2* at a time and report back.
I used to run 21-22* timing on C16 with a billet 76R@29psi. IAT's were 170-190*. I was running 9 heat range plugs as well.

I always say it and it never is the case, but some time it will help someone! I once had the exact same scenario, ran great, but a little slow....only running on 7 cylinders! Still ran super smooth.
You might try a little more timing since you are using good gas and see what the difference is, maybe your timing is off or something.

Small update,
Went back to the track a couple weeks ago. Didn't change much other than having cooler air and a hair more timing. Managed to make some decent progress.
Best 60': 1.51
Best 1/8: 6.51 @ 112
Best 1/4: 10.10 @ 139
Not all of these were on the same pass. Got loose a couple times and hit boost cut on another pass. I was still leaving really soft, haven't left on more than 2psi. I can footbrake 7-8psi pretty easy on the 2 step, just have to see it it'll stick on the track.
Found a few small areas for improvement, going back to the track tomorrow. On the 139mph pass the car made about 5kpa more boost and was jumping back and forth between 9* and 14* the whole time in 3rd gear. If the car hooks decent I'm hoping to see the 9.99 @ 140.

Yeah the table just dropped off in that area, I fixed it. I also put in new wastegate springs, makes about 15psi with the controller off and spools noticeably quicker. The ones I had were way soft before.

Made a few passes yesterday. 3 of them were total garbage, couldn't get the car to hook at all. I let it sit and cool for a while before making another pass. Did a massive burnout. Managed to get a 10.04, with a 1.62 60'. Went to make another pass after that, car hooked up pretty well and the pass felt great but a leaf or something tripped the beams shortly after the 330' so my time slip was all messed up.
Looking at the log on my final pass, I revved to 6642prm in high gear so converter slip that would still have been 140+.

I can build boost on the foot brake but it just did not want to hook at all. The rear suspension is all stock other than control arms, even still has a totally stock 28 spline rear end. Trans brake and some suspension work are certainly on winter to-do list.

Yeah a dead stock Fox suspension is lacking. You're a TF member. Look up Bob Myers and send him a PM. He has one of the best working Fox chassis' I've seen and I'm sure he could help spend your money wisely, lol. My Zephyr seems to top out about 1.55-57 60ft times before I run into issues. So it seems does yours.
