Since I didn't install a preturbine EGT thermocouple while the exhaust
manifold was out, "I'm kicking myself hard because of that stupid mistake" I
can put one in on the new down pipe I just had made. How much of a
difference is there in temps? I have noticed that my smoke has gone down to
just about Zero since I put on the nice breathable 2.5" exhaust. I do get a
really nice cloud of smoke on every cold start up though. It starts great,
nice and quick even with the cold start cable, I in just get smoke.

  1050F is pretty nearly acceptable by anybody you ask.  That covers big 
rigs too but that's the limit so they shy down from it.  I'd settled on

pre-trurbine as an absolute max, which means you rarely go over 1100F.  
Someone confirmed that 1250 - 1300F pre and 100F less post turbine was 
ok on the VW diesels.   I always like to leave a little more "room" than I'd

normally use just in case you need that little extra for a minute or less.  
come in VERY handy in this State what with the people that drive 45mph 
until you get to a passing lane and then drive 70mph all on an easily 60mph 
road.  Even I would keep it a little lower in a Vanagon though.  Probably 
1150F on a long, steep hill, loaded, in the summer.
