nice - rolling coal!
Rolling coal is useless and is the biggest problem that gives diesel engine tuning a bad name. It's one thing to have a little soot out the exhaust pipe as the mixture runs rich when you hammer down, before the engine picks up with enough boost to thoroughly combust everything. It's another to purposely roll coal, which I know this engine tune isn't made to do.

This was a video I sent to the tuner in order to have him disable the post injection. The white smoke seen is from the post injection. I have no goals of rolling coal and if I could tune all the black smoke out I would but a little is needed to assist in keeping egts low.
I've been waiting for this forever. Please PM me the info when you get a chance. Thanks

Can you post or PM me the name of the company in New Zealand that does the tuning? I would love to start down this path. Thanks in advance for your help in this. Good work on starting the legwork to get these cars to run better and get better mileage.
