PCM or ETC Throttle Body?

Hello everyone, Im asking for a little direction today.
I dropped a reman engine (from LKQ) in this Charger a few
months back. Old engine blew a rad hose an overheated.
After the repair the car has a slightly rough idle, even
surges a bit with A/C on. Car has plenty of power, no check
engine light, or pending codes. No misfires on the mode 6
data.
I did a few test runs and i noticed the "throttle % pid"
only gets up to 76%. Tried an ETC re learn. Didnt make a
difference. Performed a ETC Throttle Follower test, and same
thing, 76% max. Despite the APP 1,2 and TPS 1,2 showing
values consistent with 100% Throttle.
Test Run 1
2007 Dodge Charger R/T, ECM/Inputs/Outputs Scan Data

ETC Follower Test after ETC Relearn

Data File

Is there any way to determine if i a need the pcm reflashed,
or if this throttle body is faulty?
I did clean the Throttle body (i used a can of CRC Thottle
body cleaner) while is was off as i was swapping intake
manifolds. Also replaced the Map Sensor and Bank 1 Sensor 1
HEGO (Dealer Parts), both broke during the engine swap.
Spark Plugs are new, Champions (also Dealer).
Ive have done ETC follower tests before on other 5.7L
Hemi's, and the Throttle % Pid goes to 100%.
What am i missing here? Thanks
