Well on the way home last night I decided to get on the skinny pedal some on the onramp.  Truck pulled great egt's nice no issues, let out of it somewhat fast and barked the turbo and BAM lost my RPM gauge, CEL pops on.....ugh,  Truck drives fine all the way home so I thought eh who knows.

 

Last night I decided I also wanted to load a new tune onto my ADR to try and clean up some of the low end smoke if I am on it.  I have extra fuel thanks to the DFI injectors so I don't really need the aggressive tuning down low.  So I load the factory tune back onto the ADR.   

 

Jump in the truck this morning and my Quad says my Boost is at 11 PSI just sitting there,  and my oil pressure gauge is reading 10-12psi no change with RPM......

 

RPM gauge on the dash comes and goes, but the quad screen shows RPM fine so I know that the ECM is seeing RPM fine.  WTS is working good and I have .01 ac noise so I am good there.

 

Codes are

p1756

p743

p336

p336 or 337 cant remember

p1688

and p0235

 

So seeing as all of this happened right as soon as I let off I am all but positive that the issue is a bad ground or something, maybe I melted a wire.  

 

Anyways I will dig deeper into it later today, but I figured I would let you guys know the fun I had.  

 

Definitely couldn't hurt to know more....

Nick, when you "got on it" was it up above 3K? I wonder if the oil pressure spiked, causing it to quit.

I am pretty sure the cheap-o chinese sensor just got blown apart inside causing it to short.
