Attention: TDR Forum Junkies 
If you're keeping track you'll remember that I recently swapped out the automatic transmission for the five speed manual.
The manual transmission - at least for me anyway - just makes me more aware of the engine's function and performance.
That said, the engine seems pretty flat once it nears 2000 rpm. with a pressure gauge installed I'm only measuring about 6 - 7 psi boost.
Fuel pressure is between 25 - 30 psi at idle - which seems decent to me. I'd love to check the fuel pressure under a load but I'll need a gauge installed for that.
I did a leak-down check - turbo to intake manifold - no soap bubbles found, and even after disconnecting the shop compressor and covering the test fitting with my thumb for 20 seconds or so there is residual pressure in the system.
Now I'm assuming -perhaps incorrectly - that if the AFC diaphragm had a hole in it then air would be escaping out that allen head plug.
Am I wrong about that?
I was able to move the plunger in the AFC forward with a screwdriver.
There is air pressure at the diaphragm fitting.
This problem may have existed for a long time ; for several years I've only used it to plow snow (pretty low power needed for that ) and an occasional run to get lumber. I did tow a 6000 lb (car) trailer back two years ago and the only problems I had were a a leaky pinion seal (since fixed) and a cop who insisted I couldn't tow an unregistered vehicle on a trailer.
(Pleasant enough fellow...just sort of a dumb@$$)
I'm trying to get the truck more road worthy so the wife will stop nagging me to get rid of it.
So I hope you can help.
