With a referenced reg, the pressure with the hose connected depends on how much vacuum it's seeing, so pressure diagnosis has to be with the hose off. With the hose on you can't know if it's the right pressure or not unless you're also measuring vacuum at the same time and plotting them next to each other. Pressure with everything hooked up and under load or under boost comes later.

Funny how accounts marked as 'banned' are still able to log in and do stuff on the site, huh?
What's with the O2 sensors? If they aren't plugged in they should both read ~450mV all the time. If plugged in, lower than that means lean or short to ground. The highest I see in that log at any point is 150mV.

i think im following you i do know that i was fighting water in the tank and it stopped my injectors from working so until i figured that out i was only firing on 5 injectors witch is why i changed to decaps bc i couldnt afford another set of injectors yet lol
Upstream.
Put Fuel>Oxygen Sensors>Integral Delay>Airflow Mode back to stock. Same for >Closed Loop Enable ECT vs. IAT. >Rich/Lean vs. Airflow B1 and B2 to 450mV.
so bank 1 and bank 2 450 accross the table?
Yes, and the other settings mentioned. Relog.
10-4 doing it now thank you

here is the log after clearing ltft its running way better still not building boost though
Try again, but I think there's something going on. Clear LTFT's. Add Knock Retard to the logs.
did you adjust the tune? do i need to flash that? sorry ive had a ruff couple of days so i second guess myself
Yes and yes.
