What does a stock 2012 6.7 peak boost at?


Sent from AutoGuide.com Free App
I've been told it comes out of it's range at 36PSI and if you push it above that you're on borrowed time. I try and keep mine below 30PSI when towing, but it only hits 30-34PSI when towing heavy up a grade at HWY speed.

If you meant without any mods whatsoever then I thinks it's somewhere around the mid 20's low 30's. With custom tunes you'll likely see about 36 since the Vgt can be tuned to pretty much give whatever boost you'd like

On my stock '12 I have seen 32 peek and levels out at about 28. This is off a edge CTS monitor.

Had autometer gauges installed since day one of my truck. Mostly saw 29-30 unless I stomped on it in 6th.
