fmic's, being heavier, for one, and decreasing the response time of these smaller turbos has been understood to actually make cars slower. let alone all the hassle of all the boost leaks you can have.
< i have a fmic, on a vf30. why? my car never came with a hood scoop, and thats how the original owner fixed the problem. at these power levels it is not really necessary to have a fmic.
i think it depends on what u wana do...there is no doubt u can add more timing up top and possibly lean it out a bit more on the FMIC...will your lag suffer? of course....prolly only about 300rpmish...of course this all depends on the turbo...on the stock turbo?probably not worth the hassel, but anything bigger id say go for the FMIC
