Info on your truck would help, 1211 and 238 sound like codes from a tuned or chipped truck to me, 381 I haven’t heard of before. Maybe clear the codes and see which ones come back.

Well, does it have gauges? If so and if you can get the boost over 17 psi then it is chipped or programmed. Also if it blows black smoke when you floor it from a dead stop then it’s chipped or programmed. If no smoke or gauges and your 0-60 time is around 14 seconds or more then it probably is stock. If it is chipped then the chip can be seen in the back of the computer.

Ya it has gauges. And it blows out a decent amount of smoke. Can i buy a programmer and make it faster? Its got 190,000 miles and its a 5 speed? What should i do maintenance wise. I already did the oil change.

Fill out your signature so we can automatically know the details about your truck.

Figure out if it has a chip or if someone left a program in it, pull the computer and see if there is a chip installed in it, if not then it may have a program left in it or had the PCM custom burned. Either way, if you get a new programmer it probably will not work because of the previous one. IF you have a chip you can remove it and get a better one IF its not a good one.

Make sure your egt probe is before the turbo and not after it. What kinda max boost numbers and max egt numbers you seeing?

Maintenance wise, IF it were me I’d put a DIY intake on it and change the tranny fluid and transfer case fluid and front and rear diff fluid and antifreeze and add the anticavitation additive to the coolant and inspect the brakes, and steering system, and etc,etc. I like the Amsoil for the diffs and stuff, clean them out good and put Amsoil in it once and be done with it for about 200,000 miles or more.

Well i went to Nor Cal Truck and he told me to pull the Pcm out so im gonna do that today. My max boost is around 30 and i have never seen my egts go over 1200. He also said if there is no chip then flash the computer and start all over. I changed the transmission fluid, transfer case fluid,both diffs and engine oil.

To me 30 psi means you got at least a chip in it if not chip and injectors and turbo etc. 1200 max means your pyro is likely in the down pipe, I'd check it and if in the down pipe I'd move it to the manifold pretty quickly if it were me.
