Quote:(doing the thing yourself)...
If you are not a complete dummy with a computer (you know what a start menu is and can navigate your way around a spread-sheet, copy files, use e-mail, etc.), is to do the job yourself.

A> copy/back up the program out from ECM yourself.
B> e-mail it off to have changes made to it.
c> restore the changed program back into your ecm yourself.

It really is not hard to copy program in/out yourself. Here is more detail on this ... of course, assuming that your truck does not have a bad delete in it already and is still factory programmed, so 'step-2' and 'step 3' in this following post would not be necessary ...

- It cost you pretty much nothing, but maybe a few hours of your time to walk yourself thru it. You will also now have the proper tools and files necessary to replace the ecm and have a copy of the program so that no one can hold your trucking business hostage if u ever need it again in the future.

After that, it is simply a matter of dealing with hollowing all the cans out 100% to the bare metal (or straight piping it), putting in a maintenance-free crank case filter, and installing a block-plate of decent quality between the EGR cooler and the exhaust manifold.

Many people do this for themselves, and I don't blame them.
