1250* you can run all day long. Anything higher, keep it short...

Moving the plate (increasing fuel) will cause more heat from the combustin because obviously you are burning more fuel. Remedies are as simple as a boost elbow or disabling the wastegate, to porting the head and getting a bigger turbo.

Slightly more fuel isnt bad, but alot more fuel is going to require alot more air to complete the combustion and keep temps down.

stock plate?

You should be able to ram it full forward without an EGT issue, but any kind of power increase your trans is not going to like...
