Need help.... My truck is still chugging. It's got to stop or it's going up for sale.

I got the Predator. I plan to familiarize myself with the datalog functions over the next few days of driving back/forth to work. Then I'll let it sit for a few days and crank it up cold and run the tests and pull the cold temp data.
Good news though. Today was the first day driving it on the highway after changing the UVC's. It seems somewhat smoother at the higher RPM's. So maybe some of the little problems are fixed.
I had to plug it in last night so it would start up and not run rough this morning. It cranked right up with no problems.
Yesterday, I cranked it when cold and it ran rough as usual. I gave it some throttle and brought the RPM's up to 1000rpm. After a few seconds the rpm's raised up on it's own. I then brought it down to 1000 again. This happened a few times. It was as if the engine was slowly coming alive....... Strange, I know.
I'll find something out with this Predator I hope. If this don't do it it goes to the shop......

What about the ICP sensor? Someone suggested that it may be faulty as well.....

My 01 has 250,000 miles on it now, I have to change the Oil and filter every 5,000 miles or it comes back!!

Guys,
I'll try an oil change again this weekend and see what happens. I can try andpull some codes at lunch today.
Will the PCM store important codes and not trip the SES light? I'm asking because my SESl ight never comes on when any of this is happening. I know there are soft and hrd codes that are set. Will soft codes cause problems, yet not light the SES light?

Pulled the codes this evening. Here they are.
P0602
P0605
P1211
P1690
The truck does have a BD Diesel 60hp chip in it so that might trip some of these?
Let me know what these codes mean.
The truck is not plugged in right now. Hopefully it'll get cold overnight and it'll chug in the AM. I can record everything then and compare to what I recorded on the way home.
Thanks

602 not sure but here is something i found on it from Superchips
DTC P0605 exists only when there has been an internal failure of the powertrain control module (PCM).
Rerun Scan Tool Diagnostic Test.
This is not the tipical 603 KAM error we see on chipped trucks this is a ROM error but could still be tied to the chip. Need to take the chip out and see if the code returns.
1211 is the ICP code common with a chip
1690 is the waistgate
The Superchips tuning again set off the P0602 DTC, causing periodic power reductions and slower-than-stock performance.

Kwik,
Do you know exactly which parameters I should be monitoring with the Predator.
Most of them look greek to me. Can the Predator do a cylinder contribution test?
Truck cranked up fine this AM. It was unplugged overnight but it only got down into the low 60's.... Needs to be about 20* colder before I have any problems.
I did notice the manifold absolute pressure reading looked over-ranged this AM. It was reading something like 6,xxx kpa.It was reading this at idle. It was fluctuating between this reading and a 0 reading yesterday when it was hot and idleing.
