I'm no expert by any means but why would there be air/fuel screws on a electronic fuel injected nytro?

Ask Neil at Boost-it about this. He calls them air screws, which are located on top/back of the throttle bodies. He recommended I open them 1/2 turn from from the stock location, to improve idle after turbo install.

Have not done it yet--its on my schedule for this Saturday---stay tuned!!

screws

on the mcx instructions it calls to turn them counterclockwise 1/4 or 1/2 turn . messed around with them and found 2 turns out from being seated tight in worked best. they are not idle screws because if i turned them more then 2 it would run worse. which is my reason i call them air mixture screws. i am sure there is a more technical word for them but i am not no throttle body genius.
