TMIC will lessen the lag of you're turbo... especially the stock turbo... FMIC for stock turbo is useless because it will cause more lag... u can run bigger TMIC with bigger turbos, but there is only a certain amount of power u can extract from a TMIC... with a bigger turbo a FMIC will help because of its greater air capacity and cooling abilities... for example... u could reach like 300 something hp with a bigger TMIC and bigger turbo, but there is a limit to it... TMIC will have faster spooling, FMIC may have turbo lag, but u can reach greater hp with a greater turbo... stock turbo, keep the TMIC, once u go crazier with you're turbo mods and fuel injectors, etc, go for a FMIC...
