The other odd thing that happens, my turbo sometimes seems to neglect that it has a wastegate, and builds over 25 psi and holds it. Again no change in how my boost pressure has been operating recently. even tested it with a bicycle pump to ensure it was working. I thought it might have been my boost controller, so I took it apart and rebuilt it.
This causes less power, and my EGT to climb. The pressure will spike, then slowly taper down towards stock pressure. I can still get the same top pressures, but it does not hold that pressure, even under load. So recently, the boost pressure has not been holding to what it previously had been. This has been a great combination for producing good but not excessive power for the van. I have the fuel turned up in the injection pump, and I have the boost pin from a 1.6TD in the AAZ injection pump. I have a home made boost controller that has worked great for a few years now.
