flutting sound under load
New to forum and have a question about a fluttering sound when I am pulling up hill It starts at about 1800 RPM & seems to quit at about 2200 My truck is 2002 F350 Dually 7.3 I have a AFE air box 4" exuast & a super chip in the haul safe mode. There doesn't seem to be any loss of power just the flutter which gets louder at the lower rpms. Hope some one can help. also its a 6 speed

Do you run gauges? You could watch the boost gauge and when this occurs look to see if the needle is bouncing. If so that is surge.
You can correct this by installing a wicked wheel in the turbo.

No gauges & had it checked at the dealer but he could come up with no solution. Advised me to put the factory air box back on

Does it sound like this:

The red mustang, only my fluttering/chirping is much faster. It only does it as the truck shifts at the top of the RPM range when I'm hammering the throttle. It doesn't happen any other RPM range.

Yep -- definitley classic description of surge. I used to get it badly with the stock late-style compressor wheel, but now I don't hear it at all with the WW (also known as the early-style wheel). Another fix is the ATS housing, but that will run you about $400 or so. The WW is ~$75 +/- depending where you get it from. It has been said the the ATS housing is a better fix, but for me the WW did the job nicely.
