Thanks for that. What would you call an alarming temp, and what wold you say was the minimum mod I should do to reduce it?

Why the rear resonator? It's straight through..

Better a Decat and straight through Centre box

Thanks Tombie. I'll be checking the diagnostics more closely now. My next question wold have to be: What effect does reducing back pressure from the exhaust have on the Turbo?

Quicker initial spool up.. And mainly cooler engine temps.

Have you guys with a tune fitted a better intercooler?

Not for the 150... Have one for the 170 but not pulling the vehicle apart for a while yet.

Intercooler and silicone pipes will give the best results. I haven't done it yet because Service Agent thew out one of my hoses when I blew the little elbow which is not part of the usual kit. That made me nervous on the warranty front. Now I'm starting to think stuff the warranty.
Stranded cooling system is just ok but really you'll be happy to be rid of it.

An improved intercooler will give significantly lower intake temps. I.e 50 degrees above ambient down to no more than 10 degrees above ambient at full boost.
Those are my own measurements on my own vehicle.
I'd personally put that well ahead of any exhaust modifications.
