Code P0299 Turbo Underboost
Have A Code P0299 Turbo Underboost. No Lights On, Just Some Issues Like Excessive Lag, Stumbles Out Of A Corner. Wondering If Someone Can Tell Me If This Is A Sensor Issue Or If The Turbo Has To Be Replaced. It's Still Under Warranty I Just Hate The Thot Of Removing The A/m Goodies,and Even Worse.....being With Out My S/d

You would need to load the stock file from the SCT because they may want to 'flash' the truck while it's in. I wouldn't worry about the exhaust at all. The water/meth injection though, they could blame turbo issues on that whether valid or not.
My main concern would be confirming the service department where you take your truck has 6.0 Certified Technicians. If they don't then find one that does or you'll definitely regret it.
Do you have the stock intake on the truck?

Yes i do agree about the certified techs. I had it to 2 different dealerships when my head gaskets went. i finally bit the bullet and put in the ARP headstuds and Hypermax gaskets, since i'm sure my mods were partially responsible.

well i can tell you it is a sensor issue or that the turbo needs replacing, and probably still be wrong. cetain pids will need to be watched on a test drive to pinpoint the issue. it could even be a ypipe issue or a boost leak. good luck getting it fixed.

Me too . . .
I got the same code yesterday. Showed up when I changed tune back to stock. No boost, sluggish, poor shifting, etc. Like the turbo isn't really working.
Going in on Monday.

TIREDLR I had this same code come up on my truck, I took off the edge progammer and placed everything to stock and reset, drove truck for a few miles, no check engine light yet, But I did notice the Egr test on my OBD11 tool was always on. Any updates on what fixed yours? Any info would be grateful.
