Snow makes a boost pressure switch (#81080) set is adjustable from 2-24psi. I'm sure they work fine but with such catastrophic consequences if it fails, I'd lean toward a traditonal 4lbs Hobbs switch. You can pick one up from your local Napa auto parts #701-1575.

It's adjustable from 3.1 to 7.7psi and is a true Hobbs brand switch. I'm going to use one one these to activate my 2nd pump and set it to 7psi. At 3 or 4 psi, the 2nd pump would be turning on/off anytine I gave it more than a 1/4 throttle.

So are you buying a diesel? thats what everyone else that has gone down that road does

 

Haha, its not impossible.... we will see.

 

Any idea of why?

 

Combination of junk in the injector, inaccurate wideband, lazy knock sensors and probably too much timing

 

So you're going to fix it right?
