OTS N55 map dyno tuning day. M235i on 93 octane. Hardware of note: stock intercooler and turbo, decat downpipe+exhaust, +55whp +133wtq 4th gear pulls stock fmic heatsoaks very quickly with a tune, upgrade highly recommended! This is a Stage 2 OTS map, Stage 2+FMIC numbers will come later, expecting 10-15whp on top with an FMIC. Stage 1 runs less aggressive midrange due to the restrictive stock downpipe.
