My money's on the wastgate valve not seating entirely- carboned up seat and/or valve guide sticking up the works.
At idle, loosely stuff a wad of paper into the WG dump pipe, rev the engine a bit and see if the paper blows out. There shouldn't be any exhaust coming out of there unless you're on boost.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
