Water temp doesn't move from the normal 88-90 though..
I can't hear the turbo spooling like I can under power.
Scangauge is reading corrected boost so you may be onto something..

I'd be fitting some gauges to monitor your EGTs etc before you start all these mods

Hey did you end up fitting a Dawes or anything to fix your boosting issues or hoping the cat will fix it?

The cat wont fix your issue. I dont see 20 psi as an issue aswell. If it were 10psi i would.

It's not really an issue no, but it's not wanted.. happy with stock.
But the cat will assist the lack off back pressure and that has to be only reason why it's over spooling while coasting..
Not sure if it'll fix it or not.. I'm hoping it does but if not then it'll be valves to take control..

All rite, interested to hear how you go.

Did you ever consider just doing the 2.75" exhaust upgrade?

People seem to have a lot less issues with this on the CRD, but I think only Beaudesert sell them at around $1200, which is close to double what you pay for a eBay 3" exhaust...

Was there an outcome to this As mine (2012 CRD ) does the same boost climbs to 25 PSI
