The hot pipe is a simple and well made item from Plazmaman. O-rings seal both ends (same as factory) with one small silicone hose for flex and 2 x hose clamps. Checked this and it seems ok.
I think it may be no back pressure on turbo from the new 3" exhaust.
I purchased my first Navara 550 2 weeks ago and just installed a Redback 3" exhaust and Plazmaman hot pipe.
Scan gauge is showing pending fault code P2263 (boost pressure - performance problem) and engine has lost all power.
Any ideas on how to fix??
