Jb4 guys
I don’t know at least 90% of the things I read on here
when logging
on a 20 c43 with bcm
boost Is psi going into the manifold?
boost 2 is coming out of manifold going into engine?
iv looked at my logs and they’re usually very close
but recently I saw my boost 2 higher
any insight
I emailed BMS Sat I think but it’s a weekend so don’t expect to hear from them till Mon/Tues

You have 2 turbos. Boost 1 is driver side and boost 2 is passenger side turbo psi.
normal for them to not be exactly the same psi. if you are seeing more than 4-5psi difference between them at WOT then something is off with your wastegate or controler.

I will need to do some more logs
the one I was talking about had my pedal value -100
but throttle value was 60-40 when I was getting the higher boost2 values.
no other logs have pedal at 100 and throttle not in the high 90s
