I'm lost now as well. Might just let it goes until something really breaks.
A Good, Hard.. Run or Pull might help too ??
I know mine sure feels better after one

Didn't feel the miss on the way to and from work today. Got home and reved it up to 2400-2500 rpm in the driveway and got the miss (chip in). Ran CCT 3x no failures. Pulled chip ran CCT 3x: 1st #1 & #8 failed, 2nd #8 failed, 3rd no failures. Put chip back in.
Joe, I agree a good hard pull makes the truck run better. I have been driving this thing hard over the last couple days.
At this point I don't know if the new CPS, oil change, or IPR cleaning fixed the problem. I guess time will tell.
I talked with Jody (DP Tuner) today and asked him if the chip hid codes. He said that when we flashed my PCM to run spilt shots we only put a program on it that would run the truck. The chip programing will run the truck smoothly so the PCM may throw codes due to not being programmed to idle or fuel correctly.
I did feel the miss/vibration today on the way to work but not on the way home.![]()
???? I am getting the misfire with and without the chip installed.
