Just out of curiosity, when you were revving the engine in the video were you in park? Or how high were you taking the RPM's? The reason I ask is because my truck doesn't build boost like that while I'm in park, certainly not enough for it to make the "CHA CHA CHA" sound when I let off the accelerator. Perhaps mine isn't working as intended. But it makes boost fine when I am driving.

 

Video was in park, but tryed both ways, maybe 5 lbs boost rpms up to about 2000, at least yours drives.LOL

 

Ok ran a scan for values
KOEO
BARO 30.1
MAP 14
EBP 15

IDLE
BARO 30.1
MAP 15
EBP 18

2500 RPM
BARO 30.1
MAP 20
EBP 52

Also ran another scan still 0299 and P0478 P2263. Thanks guys.

 

That EBP looks off to me " way high " i will monitor mine again on the way home and do some wide open throttles and see how high it gets. Are you running a stock turbo?

 

P0478 C* Exhaust Pressure Control Valve High Input EP is higher than EP desired by 260 kpa (37.7 PSI) for

greater than 30 seconds.

Faulty EP sensor, VGT control valve slow to respond, Stuck VGT

valve, faulty PCM.

P2263 C Turbo/Super Charger System Performance MAP hose, MAP sensor, CAC system leaks, Intake leaks, EP sensor,

exhaust restriction, exhaust leaks

 

You definately have something going on here, its like the inlet vanes are either stuck closed or being commanded closed. What is your VGT duty cycle doing when you go from idle and rev it like you were.

 

I only captured data that was asked, so dont know vgt duty cycle,fyi i removed turbo Sat and cleaned inpected and re installed,vanes were relatively free before cleaning. Yes stock turbo 18k ago. My cousin has the scanner. So wouldnt be able to get that info till tomm. probably

 

You're going to hate me right now. I don't know why, but I have this awful feeling that you didn't reassemble the turbo correctly. I have seen it before. One that I had apart years ago, was like yours, building little to no boost. It turned out that whomever had it apart cocked one of the vane fingers onto the pivot the wrong way. Miraculously, all it needed was to be reassembled correctly to repair successfully. I was amazed that even the pivots on the exhaust housing were intact.

 

Ok, but same problem before and after removal and re asssmbly. Followed you tube video to a t and rewatched during. Is it even possible to install them backwards?

 

What was Baro reporting in KPA????? No Biggie Its not your issue Iv seen this before maybe Mike Knows what its reporting in KPA or PSI or what it is????

EBP is way High at High Idel its the Proble now we got to figure out WHY

So Im thinking BAD EBP sensor or Plugged exhaust

Tell us about your Exhaust system do you have the CAT how about the Muffler

Unplug the Wire pigtail from the EBP sensor and go for a Drive see how it ACTS does it get any better???? Im going to be on the edge of my seat till you get back HURREY LOL

 

I believe it was psi, cat was gone off truck when i purchasesed at 106,00 miles now have 128,000. Truck i s at my dads shop down road. Ill let you know. How can the muffler plug, just asking.

 

The BARO is probably in inches of mercury

 

Well I have only saw 1 Guy on here that had a Plugged exhaust its Not Common at all


Just since you have High EBP Im just looking at it from all angles that would cause high EBP reading


These newer exhaust are all High Flow

To test for this you would remove the Clamp at the Back the Turbo where the Downpipe Hooks to turbo to vent it and see if things go normal



If it was me Id unplug the Wire to the EBP sensor and drive see what that does First

I put my money on the EBP sensor going bad Before the exhaust being Plugged






Sounds about right from other threads iv seen

Does inches of Mercury convert to 14 or 15psi???

 

Ok just went and took for short ride, with ebp un plugged, it was relatively cold since i did readings,seemmed a liitle more responsive and i did achieve close to 20 psi boost, but still extremely loagy and the horror film roar of air is still there.LOL

Got a Turbo Fart going on
