yeah definitely. We got the boost controller installed and pushed it to 5psi. it will sit there while we tune. I did make one or two WOT passes at 5psi and i could tell the difference.
The first pass was fine the 2nd it made a loud howling sound and boost began to drop I got out of it quick. The 3rd pass it boosted fine for a WOT pass. Wonder what made the slip in boost on that one pass? Possible boost leak in a coupler?
