At what power output would I have to be running to need a FMIC on an STI V5 if I am simply upping the boost? I am running at 17 psi with no det (according to my KL) but at 19+ it dets a lot .... is it down to turbo characteristics & psi or flow rate combined with psi?

If I sorted the exhaust manifild/up-pipe/down-pipe/filter would that put back the need for a FMIC till I am pushing more power?

Should I just bite the bullet & go for it now!
