your going to need at least a 65 or 70 idle jet, and unless your turbo is tiny a 190 main jet is wayyyy too small.. start rich, not lean. i would drop in some 230 main jets.. what size turbo are you running? you have the black solid float i hope.. where did you get the carb hat?

The turbo is a Holset HC1. Similar to the hx40 but much smaller hot side and slightly smaller compressor side. I only plan to run 10-12 psi on this set up. I made my own carb hat. And yes I have the black float already.
