It might give you more problems. You don't want to do that, it can really throw off MAF readings. The lag is probably because of the front mount, unless you have an upgraded turbo as well, most front mounts are for handling bigger turbochargers. So you probably would get some lag using a stock turbo. This is just a guess, I don't know anything about the flow rating on your particular FMIC and there are smaller ones that would be more accommodating to a stock turbo.
