Hi,

I have been trying to work with a 6.7L that after the EGR was deleted the truck would run horrible until it got up to operating temps. Right now it appears that if he uses his edge to turn on the exhaust brake when the truck is cold it does not idle rough. I disconnected the edge with no change. I went through all the CELs and now the truck will throw no EGR related codes, however the truck continues to run rough until it warms up. I have looked through all the available tables and it appears that there are no tables concerning the operation of the EGR. I can get a log of the truck cold idling if need be, but it looks to be a turbo issue judging by how it dissapears when the turbo brake is enabled.

Anyone come across this issue yet?


Thanks

Mitch
