as mikewrx quoted earlier, and bigsky posted there after, that should pretty much sum it up, however bigsky also stated that it depends on what your intentions are later on down the road. Are you Planning on replacing the factory turbo and upgrading? then of course would you want to replace the tmic for the fmic, this is my opinion of course.
I replaced my tmic with the Blitz fmic, granted Im still using the stock turbo and injectors....I did lose some bottom end, but it wasnt as much as I thought it would be. Mid to top range did improve a bit. I just picked up the UTEC from TXS and Im now fine tuning my ecu with the mods that I have presently done. This will help as well..
