Can you get a log of that?

The log I see here looks great from what I see. Everything is where it should be and you're making 4 psi more than stock, so it should be faster as well.

It felt sluggish and rough. The boost gauge is glitchy as well.
I removed it and everything smoothed out :shrug

Boost as being read via the JB4 log looks smooth and as expected. I presume you mean the factory boost gauge? That is always going to reflect factory like boost levels, but if it's wobbling around lets see a video of that. Genrally JB4 box placement is the only variable at work here. If it gets too much EMF could cause weird behavior. Also note whether you have the issue on map0 with the JB4 disabled to determine if it's software or hardware related.

Hello there
I just wonder how can I install the connector of map sensor. there is conflict between the installation guide and this post of the forum which shows the wrong and correct installation method of map sensor on manifold ? could you illustrate which one is correct?
many thanks.

They are interchangable on this platform.
