Who would you suggest I talk to regarding some weight loss surgery for one of our emergency vehicles. It’s got an isB 6.7 and is having egr and exhaust problems. Made it to 300k but want it to go another 300k. Any help is aporeaciated

- Depends on if you want to do it yourself or not. No need to pay someone thousands of %%$$ to do that.

Assuming you live in a country where its OK do to that. I do not encourage such things, but I also don't blame people for wanting to get rid of those kinds of plaguing headaches that the OEMs themselves have no real solutions for either...

The mechanical part is not very difficult...

== Removing, then hollowing out, 100% to the bare metal, all the cans under the vehicle, and putting them back on just like they were.

== Block-plating or modding the EGR valve so that it stays closed. - On an ISB/ISC, someone can simply Drill and tap , and install single M8x1.0 metric threaded screw into center of the back-plate of the valve, opposite of the motor controller. It stays permanently shut and serves as the block-plate.

== The wiring for the cans and for the EGR should be left plugged in. It helps keep J1939 from getting open-ended, keeps the network stable, it looks nicer, and no wires hanging somewhere that eventually will get corroded all to h#ell.

== The crank case filter (above the valve cover on an ISB/ISC) also needs to be change out with a maintenance-free one, or just modified by removing all of the paper element from it so that just the outer plastic/gasket remains, and then put back in.

== Removing any intake or exhaust throttle devices, or at least their butterfly.

On the software side of things..

With a cheap adapter and laptop, someone can always just copy the program out from the ECM and e-mail off it to have that part done properly. Then to simply copying the result back in yourself. ref: http://rawze.com/forums/showthread.php?t...5#pid72945
That, or get with one of the recommended forum members listed on the bottom of that post I just linked for some official help.
