Just doing some testing (smarty ME set to stock power) and when running empty and I floor it in say 3rd or 4th, the boost will jump to 32 psi and then drop back to a sustained 22 or 23psi according to the Edge Insight. Is that normal? I thought 28 sustained was "normal". Keep in mind that is running empty, when towing it seems to have a more sustained, higher boost. I use the engine brake every time I run the truck so I don't think the vanes are sticking. Any suggestions?

 

No one?

 

i figured you were doing good at those numbers, but not having gotten off my lazy posterior and deleted yet, im not the foremost subject to comment haha

 

my 2010 runs the same boost pressure that you posted i can get it to spike for a second then it goes down to that 22 to 23 area and that is with my H&S on high

 

whats the boost in O.D.. mine in 6th gear can hold 34psi all day long
