I'm a newbie here and think this is a great thread with great info, but after reading all the differences between 2.8, 3di, 3crd and 4.2 I am probably more confused now than I thought I was (i'm no mechanic but want to do the best by my truck).

I think I might need to PM you Ferret (hope thats ok) to get the definitive on what to do to my 2012 3L CRD, but am thinking I don't want a blanking plate with a hole in it, would be like having a new bucket with a hole in it eh??

So I am thinking a blank plate (no hole) and a scan gauge connected to my OBD2. The bit I don't get is the stuff about turbo boost levels and Dawes valves and VNT (do I need that??). Sorry if that sounds a bit dumb but I just want a simple fix without having a cab full of gauges etc. I am hoping the scan gauge can give me the readings i need.

If there's an idiots guide for us CRD owners I'd be most appreciative.

I've read the thread a couple of times and just hope I'm moving in the right direction, cheers all, Mark
