Well I see a big problem with your setup.
1: Without a thermostat in that stock water pump, most of the cold water bypasses the heads and block and goes back to the radiator.
2: According to your diagram, only a small heater hose connection goes to the top of the radiator. You should have a 1-1/4" hose off the water pump goose neck going to the top of the radiator.

Sorry Cyruss88 ... I am do have a 11/4" neck on the stock water pump. With regards to not using a theromostat here are the instructions on the TinyCWA manual .
Use a thermostat or not?
It is possible to use the pump / controller in combination with or without an
ordinary mechanical thermostat.
If you use one just make sure you set the controllers target temperature as
close as possible to the temperature of the thermostat.
(Of course you can play with the target temperature a little for eventually
better cooling results.)
A cooling system with a thermostat can benefit from an even shorter warmup time and a more exact actual temperature.
A system without one on the other hand got fewer mechanical losses but
the actual temperature can vary a bit more from the target you set
I may just need to lower the target temperature.[This message has been edited by str8maxn (edited 04-25-2022).]

The stock LT-1 water pump is not an ordinary mechanical water pump found on the old SBCs.
It needs a thermostat or another way to block the internal passage between the hot and cold. Look up the water pump description on the internet (or run water through a spare/junk one and you will see) .

It does not matter weather is an LT1 or a SBC. The Tiny Controller is more intelligent than you think. You can put a straight pipe to bypass the pump an with the right setting the Tiny will pulse the electric pump slowing down and speeding up or block flow as needed to meet the set temperature.

I installed the thermostat and lowered the temperature setting on the Tiny controller and got higher temperature readings.
Plus it seemed to get to temperature a lot quicker.
La Fiera, Are you running the stock Fiero radiator?
Cyrus88 Same question?
I am up in the air as to what to do next. 3 Row radiator , pull\leave the thermostat and play with the setting

I'm running 3-core champion radiator, stock fan and shroud. Car runs cool as a cucumber.
couple of questions: do you have the heater hose routed correctly? Is the steam line from the back of the heads installed and routed appropriately?
If I were you I would eliminate the stock water pump and use hose adapters.

Oh, one last question: Are you sure you have all the air out of the cooling system?
