Current codes p2579, p0107, and exhaust service needed see dealer now

[Controlled_Pair253]

Hello gentlemen and ladies.
First post, haven't been able to find anything that is exactly what I'm running into. 2010 2500 G56, 147k, motor ops tuned at 115k,csp5, cts2 edge, deleted everything, 5" flo pro, pusher intake horn, Rudys diesel performance cai, CCV delete with reroute, brand spanking new batteries, and MAP. Recently I've been getting a exhaust service required see dealer now. I've read that this can be caused by a plethora of reasons. Also receiving the "red lightning bolt". MAP was replaced yesterday, CCV gutted yesterday. The truck would go into limp, I'd D/C batteries for 10 minutes reconnect. attempt to read the tune (received a $0281 from the autocal) went through shut down procedure, changed tune, started truck with no CELs or the exhaust message. This has been an issue for about 2 weeks now. Anyone have a clue as to what the hell is going on. Or a cause. Since it was tuned the p2579 has popped up consistently, which would clear with the edge, however whenever the CEL was cleared, the boost would not register on the edge UNTIL the CEL popped up again. If anyone can point me to a fix that works, I'll but you a year towards platinum member to igotacummins. Thanks.

So for the p2579 it's basically saying the turbocharger speed estimate is more than the calibrated estimate. And then the p0107 is saying the map sensor threshold is below a calibrated threshold for too long. I'm going to go out on a limb and say you should contact your tuner. Esp since it started after tuning the truck. I'm not sure what all they change when they tune trucks but ide say he didnt get something right. If I had to guess the map sensor code is coming from the 2579. Could be wrong. But I would do that before replacing any more parts.

The 2579 is supposedly typical after tuning. The truck has been tuned for quite a while now (about 1.5 years) , as this is only a recent issue. There is 5v going to the MAP with the truck off, so I know that it's getting the correct voltage. I am going to give motor ops a call here shortly. I know that these trucks rely heavily on a solid electrical system. Im wondering if it may be the alternator allowing for a low voltage scenario in the MAP. In retrospect however, how would this issue play into the exhaust system service message?

Not sure on the exhaust message. Doesn't make any sense to me that a tuned and deleted truck would be able to have that message even come up. Ide be asking them about that also. Probably all tuning related i would imagine. Let us know what they say when you call them. Its definately not abnormal for multiple codes like that to pop up and be triggered by one issue.

I know sometimes things dont make sense at all. Like last winter some dude was flying and hit black ice. And then hit the right rear corner of my truck. Same day had a p0420, excessive engine noise, and reduced power. So I'm thinking it was from the accident but in turn it was all a software update from the dealer. Just an example of how things happen but make no sense and aren't even logical LOL

Welp, motorops is closed today . I'll probably call them wednesday when I'm home. At any rate, I'll update this. It is super weird how one thing can lead to another and have nothing in common. I'll update when I call my tuner.

I agree. Contact your programmer if everything is in order

I was one of the pioneers in deleting the EGR 11 years ago

I just blew through all this. Eyes are still not back to 100%. This limp mode you describe. Is the EGR disconnected? Does it come. and go? When you have it, can you step on the pedal and it will go then go back to the limp? If so, is the flapper valve unplugged? If not, there's your limp problem. It's not limping, it's trying to Regen on the hidden timer in the ECM software. The flapper is closing and cutting off the Oxygen to the engine.

Stop throwing parts at it. We don't like to waste money here

The truck is completely deleted. The egr is in a box in my garage. The issue has not gone back since I did the CC filter delete, and replaced the MAP with a Chrysler OEM unit. That's not to say that the tune doesn't suck though, because it does.

Still, check that flapper. If it's plugged in, that's my bet. The EGR deletes originated on the 07/08's. A 10 is the same with a different skin. Having been through this a hundred times, trying different things, and coming up with different ideas, some semi successful. It wasn't until someone broke the inscription that software was able to help us.

I deleted the flapper as well. I have a pusher intake. Or am I missing what you are saying? I don't doubt you iaff that issue, but just wondering if it really related to my problem in this case.
