It's funny to see some of the problems that people are having with the isx. I have 1.5 million on mine. All government crap taken off. Deleted and turned to 575hp. Mechanic called it the firemans code. We have a kenworth with a c-15 with a c-16 code dynoed at 600hp. With only 275000 on the motor. And the cummins spankes it on fuel milage and power. And the cummins DON'T burn any oil and the oil stayed clean. Holset turbo added. And I have a yearly overhead done. I weigh 95000 regularly on a 7 axel truck. It's an 06 international 9400i.
