temperature gauge just above half way. normal?!?!

[2056515]

i replaced my radiator with a koyorad. i didnt bleed the air out properly and car overheated on me(not hot to the point reading H on temp gauge or steaming). so i bled all the air out and the temp gauge will sit just above middle on temp gauge and never move at operating temperature. so i replaced my thermostat with a nismo thermostat and it is still reading just above middle on the temp gauge. so is it just normal for 240sx to b running at that temperature or is something wrong with my car?!?! my fan works. i have pretty close to 50/50 mixture of antifreeze. any help would b appreciated. thanks.

it should be ~middle of the temp gauge. that stock temp gauge sucks since it's temp sensor sucks. There's another cts that the ecu uses, it's got more accuracy.
