you NEED a FMIC for a stage 2. The turbo gives off too much heat and the stock SMIC intercooler cant keep up with anything over 200bhp and wanting to push stage 2 mods.
If your going to go stage 2, do it right and get a FMIC and take full advantage. Last thing you want is 50C+ temps pulling timing so far back your still at stage 1 power.
