Default 9psi on map 5 - 08-21-2019, 09:34 PM

So I have been running map 5 for some time (basically since install), and assuming the hijacked fuel gauge is correct, Iím only hitting between 8 & 9psi.
So my initial thought was boost leak, however the other day I went to pass somebody and floored it. Upon revving up there was a violent stutter, followed by 18psi. After that it continued to pull fantastic. Shut down for the night, now stuck at no more the about 9psi again.

Wondering if Iíve got a setting messed up. Is there a recent map guide available?

We'd need to see a log to really assist.

One thing to double check would be to make sure your jb4 is set to 4/3 (tach) if you arent using a BEF or 4/2 if you are.

Get a data cable & throw up some logs.

You are boosting 15 PSI, not 8. Look at target and actual, not ECU PSI.

I see that, the 8 psi was based on the highjacked fuel gauge for boost, before the log.

there is some hesitation several times throughout the rpm range that id like to track down as well. I want to say that it was the 2nd or 3rd pull
