2006 6.0L low boost???

[blk00gtvert]

sorry for the newbe question but somthing i noticed. I originally borrowed a friends 2006 F250 with a 6.0. while i was driving it i noticed that the boost under full throttle read 25-27 PSI. i liked his truck so much i decided to get my own. i bought a 2006 F250 king ranch and the first thing i noticed is the boost gauge NEVER goes above 16 PSI. i installed a EDGE Attitude controller and even on the EXTREME setting it still never goes above 16. why is there such a big difference? is there somthing wrong with the truck. by the way my friends truck was a job 1 while mine is a job 2 if that makes any difference. thank you for any help you can offer.

Are the power gains there? If so you have a guage problem I would say. My friend has the edge with attitude and he pulls around 38 psi boost. his is an 04'. Do you have a aftermarket intake? that would cut it back also if its still stock. Might not be able to get enough air.

Whats stock boost for the 05+ 6.0L ? 20? Only thing i know most guys on here say to not run over 27/28 on a stock motor... hope your gauge isnt broken and your really boosting 35psi lol.

stock boost should go to roughly 27 PSI on an 06....

I would wonder if you dont have a gauge prob though, does your truck go as good as your buddies?? If it does, its not the turbo, its the gauge...

If it is a turbo problem, it could be a Y pipe leak, it could be a boost leak, or a stuck turbo...
