It was my mistake. I should've replaced that hose while the engine was out. I have a newer one sitting on my other engine in the garage. I just really hate that hose.
And I can't really push the 57 at all until I get a wideband and a fuel controller. I'm going to turn my AVCR setting to OFF and let it run off of wastegate alone. My only fuel mods are the Aero-AFPR, Walbro, and fuel dampener bypass line. I drove around the block with the Lexus AFM on and it idled fine and drove good, just studdery when I get into boost higher than stock fuel cut levels. I put the stock AFM back on.
