So true, but the "potato in the exhaust pipe" test was to see if the wastegate was stuck open, allowing exhaust gas to escape instead of following the desired path to the turbo. All irrespective of building 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.
