Isn't that a bit too high?

Don't you experience problems with gaskets and seals?

This is the default setting. the default value for the idle 2.9 bar.

Renault 1.9dci measured. 2.0 bar at idle hot. Raised speed 6.0bar

You can lower IAT a lot by using cold air intake. Having an air filter behind an engine cooler raises IAT temperatures and lowers MAF at the same turbo boost...

I do need some more pictures of the installment and fabricated boostpipes if possible :lol:
accidently I just placed my BMC CDA airfilter in pretty much the same location today, after years of having it behind the engine, I just felt like changing it ;)
Cuurently rebuilding one of these with a gt1752v, 110 injectors with bmw 325d nozzles and an audi 2.7tdi fuelpump...
still trying too find a suitable mapsensor, as I wanted to keep the factory pipework, but will nearly be impossible...
