Hello E90post and thank you for your taking your time to help a fellow member out.

I installed my JB4 G5 after getting a clean bill of health from my dealer. I replaced a Solenoid sub-connector and installed the tune without any hiccups. The next morning on my way to work I had a half engine light appear on the dash while using Map 5 and I was only receiving 5psi of boost.

Now I cannot give more than 70% throttle without the half-engine light appearing. I have since logged three runs and emailed them to BMS.

Just now I removed the tune and the car is still staying under 5psi of boost and continues showing me the half-engine light

When I read the dme I had a code
Code: 38A4

I have searched for hours about what to do next and I am basically stuck.

Thank you again for your time!

I think that code is for the intelligent battery sensor, which monitors the health of your battery. I'll let somebody else more knowledgeable chime in though.
