Mr. Hag in atlanta is not a bad option if you want to take it somewhere and have it done right.

This is something that I can't understand at all and fortunately or unfortunately 530hp is very popular. As of today I am 95% sure that 8521 "out of box " can not be used on 6/6 CPL listed engines. At least it felt like that, with metallic detonation noises of my engine.
This 2 cals identical inside
AB10349.23 is 8521 (6/6 possibly)
AB10351.23 is 8518 (6/4)

For me its not important anymore after help of Rawze himself to get proper cal and parameters I wanted for my ESN, for others it could be catastrophic, could be not, I dont know...
Just wanted to bring some attention to this matter because I know in person {shop name removed} who is putting that cal into all their customers trucks no matter what based on 1 thing: its made for 6/6 by Cummins :(

The red engine maker was playing around with wedge offsets during those early CM870 days in attempts to get the higher HP engines to pass emissions standards.

Those 2 programs are indeed identical internally, yet the CLP's call for 2 different timing wedges. - Possibly a mistake on their part? .. or something else ... Only the red engine maker knows why this is, and/or how hard it would be on the engine itself at the end of the day.
