This explains why the engine would derate and blow a bunch of smoke when I would push it uphill. I've kept the turbo at 30 PSI max and it has not done that since.

These enigne cannot handle more than about 4 or 5 at 600HP... and only about 3 at 700+ HP... this thing is severely destructive! -- You sure this thing is not a copy of one of those big-name big-time delete companies like the one in colarado or utah!>>??? ... Because this thing looks exactly like their kind of rotten, complete engine killing butcher jobs!

I wasn't informed when it was done, but this was done locally in Southern California. I will reach out to previous owner and find out when it was done. It could be that this shop copied an ECM from a truck done at one of those shops in Colorado or Utah.

It was purchased with the bad programming.

I will email you the serial shortly. As for the ABS, I noticed a cut wire underneath the dash with an ABS label on it. Could that be the reason its not communicating or does it seem to be wiped from the ECM completely?

Engien may seem to run and likely seem to "pull ok" but it is set to completely rip that engines guts/liners out!. I see that you've been getting 7+ mpg (meaning you have not been running it really hard) according to its data .. but that is also being fooled by the bad injector quantities and fooling it into showing more fuel mileage than its really getting. It not being run hard is the only thing that has made it last this long so far.. however, if its been driven on this garbage for a while... I seen liner fretting issues and other head problems (or a cracked piston) in your near future!... If it does not send a piston thru the block without any warning that is.

What would be the best course of action to revert this program to the original? Would a dealership be able to flash it back to stock given the serial? Would that include the OEM data you mentioned earlier in this post?

Thanks!
