On TunerStudio dashboard you can add a gauge that shows you sync loss count. That's the easiest way to see if you are losing sync, besides the tooth logger. It should basically have no sync loss except 1 count every time you "burn" a change to the ECU while it's on. IE if you have the car on for 10 minutes and you burn changes 3 times to the ECU, it should show a sync loss of 3. Anything more and you have an issue.

I’ve found a fuel pressure gauge or sensor is the best place to start there. Don’t swap pumps until you’ve verified it’s the culprit.

It pulls hard up to 5000 power is great. After that she is still floundering doesn't fall on its face but it's still missing. Sounds like a wet distributor cap so I've got a new cap and rotor I'm about to through in there too. Edwardo estimated 170ish to the wheels once the fuel supply is there. I'm doing the injector swap now.

Also you can put it on a TS dashboard. Hard to use while driving though.

you are hitting the rev limiter. If you look below it says SPK: revlim retard(deg): 2.7. It takes 2.7 degs from your base to get 34.3.
It's a 2 valve head with a little quench... 36-38-40 is probably in the realm of "correct" at WOT after 3k. To know for sure, you need a dyno, of course.
You need to change your required fuel in your general settings after changing injector flow rate. You also should change dead time if you have it available. It's not the end of the world if you don't have it. It's not as important as some people make it out to be'84 318i M10B18 147- Safari Beige

I did reset that and I believe my problem with the cutting out to be the gap on the cps I'm gonna reset it tomorrow morning and I'll report back. If it clears up its back to the dyno to put down closer to 200!
