I don't know the exact dollar amount or what he purchased, but my son has HP Tuners software and has the ability to turn off vehicle anti-theft, EGR and other things. Just have to purchase the "credits' to do each vehicle. He isn't well experienced with other aspects of tuning, but is looking into things. He may be able to help you.

Oh! And yes, the 1/2 tons went GMT800 in '99.

I'll holler at ya in the next few days, to talk more.
How was your camping trip ?

We just did a day trip to the San Juans. It was great!
That cam will probably run decent without many changes. Not perfect, of course, but it should run.
Now, it will probably trip the CEL for random misfires because of the idle. It takes a few adjustments to make that stop.
I don't know of anyone in the valley who can nail the programming 1st time. But maybe I just haven't dug into it enough.
