It's going to be up to cust if we run it unplugged or dive deeper.
Like said it's an 05/06 with egr doodled but he claims it was never tuned but no cel and no 1408 egr codes... It's got to be tuned.
I even pulled over, plugged back in and didn't make it 150 ft and knew the issue was there, turbo over boosted and low power. Unplugged, then rung every gear out 26/28 psi awesome power, can even lug it in 3rd and it'll spool right up.
300k miles, original injectors.
Denso starter
5w40
Stancor relay and motorcraft glow plugs.
No issues starting when in negatives for days, not plugged in..
No egr, he claims no tune but the cooler is gone but it nevers throws egr codes like 1408. It's a manual straight exhaust... The truck acts like a plugged cat
13.9 ebp cold with shit sensor. 14.5 with new oe sensor.
Cold the vgt shoots to 84%, after 1 min now 75%.
Cold idle ebp 17.2
Vgt drops to 14.99 during event and the exhaust sounds like machine gun, popping and such.
