406 2.0hdi 90 turbo adjust

Post by Imissit »

What is the original boost on a 2.0 hdi 90?
And would it be very damaging to the turbo to adjust it up by 0.3-4 bar?

Pretty sure the boost is controlled by ECU so you cannot simply adjust it yourself - only by remap.

On the 90hp it's mechanical, 110hp is ECU controlled. Standard boost is about 14psi. Without adjusting the fueling you won't see much gain.

Indeed, remaps are more about injecting more diesel than going for high boost (they run high boost anyway and because there's no throttle butterfly you get maximum combustion air at all times).
