Having heating issues with my boosted teggy right now. ECU picks up code 11 which is my over heating code so it wont let me hit boost... but when i look at the temp guage on the cluster everything seems normal.
It's bored over to 81.5 could that be a big reason for all this extra heat?

Starting to question my mishimoto halfcore radiator as well... Anyone ever have problems with these radiators maybe not doing a good enough job cooling? What radiator is everyone running?

 

Nothing wrong with the mishimoto. You have poor air flow to the radiator and more than likely an undersized radiator fan and air bound coolant system
