Loosing coolant after AST delete

Loosing coolant after AST delete
Hello all,
I got my AST deleted with longer neck and 1.3 bar radiator cap. When the car is hot it seems to squirt a bit of coolant out. but that stops after probably about 10oz of coolant lost. If I don't fill it up, it's fine but if I do, it will squirt again.
my theory is that may come from the radiator cap. is 1.3 bar enough? what do you think causing the problem?
thx

The original cap was 1.3 bar.
But Mazda's original water hoses were poor quality and along with the high engine heat, there was leakage and fires. The recalls if you looked them up, included some new hoses and lower pressure cap of .9 bar.
Just as the first engine wiring harness was of poor quality.
With all the improvements that we have done to our cars over the years to reduce heat and improve air cooling flow over the engine, many have gone back to 1.3 bar.
1.3 bar is used on many cars. Helps reduce engine hot spots boiling.

When using a pressure cap with the hose connected to a overflow tank, wouldn´t the pressure cap prevent the cooling fluid to re-enter the cooling system once the engine cools down again, causing the cooling system/engine to be low on coolant when first starting the engine?
