Struggling to figure out how to use jb4.

Cant make over 18psi.

Tried map 1, 2, 3 and 4.
Map holds spring pressure 14psi to redline.
Map 2, 3 and 4 make 17 18 psi.

Logs are weird to me on jb4. Wgdc shoots to the moon but turbo doesnt sound like its working hard at all.


Asked for help on jb4 forum see what happens.
