Soooooo...this truck is driving me crazy.  Running through the gears (it’s a 7 speed) it’s only making 15-16 psi.  Then once yesterday and today I’m in high gear, empty, around 55-65 mph and it hits 22-23psi.  It’s only hit that much twice.

All connections are good.  Can’t find any leaks in the cooler.

Just installed a boost guage and plumbed it to the manifold.  Running 15-16 psi.  That as good as it gets?

I just got an 06 Granite and the steering seems a little lose compared to my RD.  U joints look good.  Was just wondering if there was an adjustment on the steering box.

Awesome info here.  I really appreciate it. 👍🏼

So, a 350 would have the same injectors as a 300 based off that info?  Forgot to mention truck has a 10 speed.

I’m looking at purchasing a 04’ CV713 dump and it has an AMI 350 in it.  Was wondering if it could be turned up to 400. Thanks
