Not on the dyno but as soon as my tuner sends me the log file from the track run I'll see maybe it's different in real driving.

Looks pretty good to me!
What psi and RPM are you launching at?

So we took timing out between 2600-3400rpm so that I could load it up in 1st gear, I was actually seeing 9-10psi but realized after looking at the scans and seeing it in the video we think we're pushing through the converter so that's why it's not leaving as quick as we would want, kinda of laggy off the line. I would likely be better off keeping it at 5psi instead of letting it go all the way.

Update time!!!

On Friday night it was cool and not busy so was a perfect night. I showed up and did a 12.006, then my next run was 11.965, I was very happy but I knew I needed to back that up with another sub 12sec run so I did a few more runs and hit another 11.97, SWEET, even the guy handing out time slips was rooting for me.

That run also had a worse 60ft time + right at the end of the track I felt the truck lose power a bit then pick back up so she has more in her for sure. Might need to change out that stock Flex Fuel Pump I'm thinking. I did about 6 runs and had no knock at all, overall a great night.

Here's the slips and a video, sadly didn't have the best camera for night time shooting but you get the picture

Thanks all, yeah it was in 4WD and I kept it in 4WD the whole way down, I thought of trying to switch it into 2wd after it shifted into 2nd but didn't want to risk it (is there even risk to doing this, I don't know?)

I will update my sig now
