Remap benefits??

[Dr Gary]

Will a remap on a GU 3.0 Di make much or any difference?

On a Di I doubt it. The CRD's are a different story. The CRD's i believe they can adjust rail pressures etc, i don't think much can be done on the Di engine apart from deleting the EGR and limp mode for over boost. I could possibly be very wrong though.

[Dr Gary]

Pretty much as I suspected.
Already done the EGR and cured the limp mode with a larger inlet around the MAF sensor.
