Does not make sense to me to put on an aftermarket fmic and run stock boost.
I experienced a loss of power in a car running stock boost as a result of upgrading the fmic. Which I have to attribute to some natural pressure loss due to the increased area inside the fmic.The purpose of upgrading the fmic is when running higher boost the charge air is less likely to heat up like it would with a stock fmic and running higher boost levels.
