Was toying with the idea of using this housing as its 6mm bigger than OE

Providing your maf will fit into this housing and you can adapt this to your vehicle, there is no reason why it would not work. I saw these a while back before I got my HPD housing. Laziness got the better of me though...

Edit.. the Hume hwy out of Melb is 110 kph max on the way to the Murray.
so for me anything around 12-15 psi would make me happy

Depending on chip, the DS chip does the same as the HPD housing, but in the electrical side of things, and I don't think you can remap the DI ecu. I think...
I'm going up the Murray on Thursday with the camper in tow. At 110k, on the flat, I usually sit on around 18psi.

No problem.

Just took it for a decent run and some hills and it is spot on. Maxing at 19 to 20psi. Not sure why it is so different but don't really care. I will hit some tracks next week down at Lithgow so see how it goes. Cheers

Good to see mate. You can now kiss limp mode goodbye, forever.

Would be easy enough to whip up a new MAF housing, OD is 3.25" so
Ive ordered a 3.25" to 3" reducing hose, That Skoda housing has
a maf Hole in it is about 34mm approx. Skoda maf housing 1.7mm bigger than HPD

Or skim 3mm out of the OE housing

Is this mod only if the car is going into limp mode? Would a CRD benefit from using it?
Looking on the HPD's web site they only have a model for pre Aug 2004 and Aug 2004-2008. This would include early CRD's but not the bulk of them. The site only mentions ZD30DI models, not CRD. My car is a 2007 and I suspect its using the same housing as the DI's but I do not have any limp mode issues.
