Cm870s don't suffer from overheating issues from removal of the egr cooler and freeze plugging the ports or water pump overloading, BUT those boost levels will destroy your engine in a hurry! Did you change the boost pressure sensor and exhaust pressure sensors and clean the tubing to it? Is the turbo OEM VGT and does the actuator arm move freely on it, if not and the turbo is hanging up could very well cause your boost levels to go to the moon and engine to pop and backfire like a machine gun until you back off of it.. mine did that... DEFINETLY get your file checked, you're on borrowed time if you keep driving it!!!
