Does anyone have any readings from a stock 04 5.9 with an HE341 Holset for an average boost pressure? just wondering I haven't installed guages yet but going to when I get home in a few months. just wanted to know if anyone knew how much boost a stock setup was making? or possibly how many cfm the HE 341 flows? thanks

I believe the 341 will push 22-24 PSI.

I installed an adjustable boost elbow on my truck's 341 and can hit 35-37 PSI.

 

^^^correct. It has been known to push 18-24psi depending on elevations, weather, density, etc.
