Constant high idle when moving off throttle..
Sup guys.... did a head, intake, TB install the past weekend. Car runs great and all my LTFTs are in check. Only problem is that when I'm like rolling down a hill my car will idle at 2k until I come to a complete stop. Even when I'm cruising and just throw it into neutral it'll do it as well.Do I take care of this in the idle airflow vs. ect??

That is because your base running airflow is too high (and/or your throttle body blade is cracked or drilled too much). Your idle trims (at least your ST, I am not 100% sure on the LT, but they move REAL slow) don't affect your base running airflow once you start moving, so you get hit with the full base running airflow table, plus throttle cracker.
Basically you need to tune your base running airflow and your TB.
