P0234 - Guys with little/no boost tapering

Guys with little or no boost tapering till redline, are you getting the P0234 code??

When i used to boost taper before i modified my hallman mbc, 20psi to ~17psi@redline, i never had this issue. After modifying the mbc, i eliminated the tapering, but keeps getting the annoying P0234 code.
