[mattdriver1234]

just got my truck studded egr delete oil cooler coolant filter stc fitting ipr sensor and truck is puking still tech had heads checked was in really good shape. I have the tea kettle sound and coolant only pukes when running Erics extreme street when stock does not puke but still tea kettle sound. I now know to lower coolant level when running hot tunes. also pulled the return line to degas bottle on cold start and and was getting quite a bit of air so im confused and wondering what else it possibly could be or might be HGs again tell me what you think thanks.
