Fuel system flushed
Boost sensor/lines, cleaned, checked, changed, bypassed- no difference
Injectors replaced
Filters replaced
Egr plugged
Cat bypassed with straight pipe
New air filter
Trap Ox replaced
No play in turbo fan, turns smoothly
etc...

So- now I am removing turbo to check and clean the wastegate. I have removed the egr, the trap ox replacement pipe and am a bit stuck. I have read that I should take off the exhaust manifold and turbo at the same time, but the turbo is in the way of the nuts so is there some other way or some fancy method I am not thinking of??
A turbo doesn't provide any boost below 2000 rpm, so replacing it isn't going to solve a problem relating to climbing an incline from a dead stop. Any W126 diesel will climb a fairly steep incline effortlessly at 1500 rpm........well before the turbo contributes any assistance.

What's the 0-60 time on this vehicle?

Does it have power at 80-90 mph..........or will it not make 90 mph without talking nearly forever?
