your best bet is to call your tuner to get a base map for the 850's so you can install them now.

did you install the turbo without any kind of tuning or supporting mods?

You probably also need to check for any boost leaks or exhaust leaks before your tune. The car should run fine and drive around fine on the stock injectors, as long as you stay out of boost.
