i hated the FMIC, the lag is around 600-1000 rpm. no tuner can remove that, the only way to reduce it is to play with the pipework diameters, bends and angle mounting the turbo to optimise the flows and velocities of the air.
if i had my time again i wouldnt do a fmic and would go a large water/air barrel cooler.
