14* of timing, need to add some fuel, seeing about 20* of boost max. This was off idle.

Car feels like a beast. Need a better 60’ but prep is what prep is.

The air is not that good, saw 21-22 at max. I've definitely exceeded the airflow model. Car turned off on a hell of a rip. Coasted to 9.7 @ 138 with a 1.3x 60', she was scooching. So fugging pissed.

Hmm maybe missed a table. I’ll post a few tables later for you to check.
I think I sent you the engine diagnostics ones but did I send you the ones in the engine tune?

Your issue is mechanical, not tune related. Swap out the bypass valve with a fresh one and hope it performs better.

I don't think it's related, but I do see your INJ PW increase above 6300rpm and fuel pressure begins decreasing at the same time going from about 80psi down to about 71psi. It's not causing the bypass to open that I can see, but that's something to keep an eye on as you're taxing the fuel system. I'd add the pid "desired fuel pressure" so you can compare commanded to actual. Mine is always 80psi for both and fuel pump duty % never goes over 85%.

How'd you shorten the time torque is removed at shift? Yours looks about twice as fast as mine.

If you're building a race car th400 this but if you wanna keep it steerable I'd look at Dave's or Sipples built 8 speed.
