I think there's something else wrong. I've never had a free flowing exhaust system cause an EGR code. It may be getting pushed open with high boost pressure.

Lots of good info here: http://www.hptuners.com/forum/showthread.php?36318-Idle-Tuning-How-To-amp-Guide-%28w-pictures%29
The LLY tune lists 3300 rpm, but the LBZ tune lists 3250 instead. Not much difference, but it made a direct copy a little more difficult. I double checked the boost tables and its set up like I...

Every LBZ file I found in the repository showed a different OS than my LLY, so that's why I thought they were different. I also noticed some of the tables had different ranges than mine, which made...
I would like to update my 06 LLY to the LBZ OS. From what I've read, hptuners can't do this for a diesel, so I'll have to do it at the dealership. I work for a GM dealer, so that's not a problem. ...

Balance rates are trying to even out the engine rpm to give a smoother idle. If there is a weak cylinder (low compression), it may also cause the balance rates to be off. I have rarely seen the...
