2011 Ford F350 6.7 turbo boost increases then decreases

2011 Ford F350 6.7 diesel. Issues with toubo losing boost when driving. the boost increases then decreases all the time. It almost sounde like air leaking and some exhaust noise coming from the engine bay while its cycling. yes there is some power loss while this is going on. Any help!

have you checked the inter-cooler tubes for leaks?

Have you pulled the codes? Might be a waste gate problem.

under the hood inspection of all turbo fittings, boots and the intercooler tubing is needed. Rule out any leaks by checking for soot. You can run it and listen as well. but check it over first without running.


I'd check codes too.

Thanks for the response. I have checked the inter-cooler tubes, and replaced one. I haven't checked the codes yet, but I'm looking into buying a reader. Would you recommend the

AutoEnginuity Total Ford Scan Tool Package Enhanced Bundle ?

yes I would, just ensure it is the lastest so it can read the year of the truck. It should though.
