With POD injectors and a tuned pump, I would assume the Pyro gauge would really be the one too be looking at in the video.

Big turbo, big intercooler, EGT's don't get much above 900 (after turbo). I was just making a joke. I can hit 90 in 4th before I have to shift into 5th. The truck hasn't had an easy life with an almost senior citizen delinquent pulling the levers and pushing the buttons for 460k miles.

Like to see pictures of that "'85 W-350 crew, '90 12V/NV-45, HX-35, 24V intercooler, tubes, boots and I-horn, airbags over springs at all 4s, 3.07s"!

I redline the 3,200 spring at 90 mph in 4th, 5th buries the needle.

Blow-by in your truck could be caused by several factors such as worn piston rings, cylinder wall damage, or a malfunctioning PCV system. It's important to diagnose and address the issue to ensure optimal engine performance. Consider a compression test and inspecting your PCV system to start.

Mine must be stuck, that would probably explain the odd vacuum readings i see when plug the ECM into the scan tool.

I think I removed my system when I bought the truck? It's probably in the pile with the distributer I took off at the same time.
