[Vwdiesel] Someone should try this

Boost compensation isn't that critical. All the boost aneroid does is
reduce the fuel a tad until full boost is present, so you don't annoy the
California clean air bunch with a mild puff of grey on acceleration.
Without an aneroid, the boost actually comes on faster, because you get more
fuel quicker, but cannot avoid the puff of smoke initially.
Total fueling governs exhaust gas temp, and if you are going from stock NA
that doesn't blow black clouds at WOT to a turbo without changing the max
fuel setting, the egt will actually be cooler. No harm will come from that.
If you were to dial in more fuel without using an EGT, well, then there is a
very real possibility you will go beyond the ability of the pistons to stay
solid, with ensuing entertainment and expense.
I would think that this turbo setup would be the absolute ideal for altitude
compensation, much like an ecodiesel was all about improving Volumetric
efficiency. but again, with long steady steep grades you REALLY have to
watch the temptation to overfuel and kill the pistons. I'd stay under 1050
degrees preturbo and all should be well.
