newb L83 idle issue

I'm a newb to gen V tuning and I know enough gen 3/4 to get me in trouble. So when your explaining, talk to me like i'm 5. :). Now that that's out of the way.....

I have a 78 C10 with a L83 swapped 6 speed manual running a E92 ecm and harness from PSI conversions for my application. I am not using a fuel pump control module so i have a regulated 74psi to the engine. The truck runs/ starts no issue with good power. I have a hanging/elevated idle when letting off of the throttle. Annoying to drive since the rpms jump up in between shifts and occasionally elevate to 3k while at a stop. Putting a load on the engine by letting out the clutch will bring it down but can re occur at the next stop. I've contacted PSI and they stated the idle needs to be "set". I have an autel Maxisys and HPT. I've done the "idle set " and throttle clean with no luck.

Open and write entire. Your background throttle body tables weren't set correctly for the 5.3 tb and intake manifold. Companies shouldn't just say it needs this or that when they don't have a clue what they're talking about. You'll have to re-tune everything from here, but should hopefully help you since it'll actually know what it's got.

I only changed your throttle area and etc scaler tables in the background.

Wow, so the base calibration is for a 6.2 still? I was told it was flashed for a 5.3
