Air Noise

[redbird]

I just recently installed a cold air intake kit on a my 2000 F 250 7.3. Hooked up the fifth wheel on Friday and headed to the campground. Now whenever the motor winds up and changes gears (auto trans) I hear what sounds like air pressure being released when the RPM's drop off at gear upshifts. Everything seems to be installed correctly/tight. Only electrical involved was the temp sensor which was reinstalled in the new airbox as per directions. Never heard anything like this with the stock air box. Is this something I need to be worried about? I don't want to be driving it anymore until I know what's going on. I'm not real familiar with a turbo or the workings of it. Any ideas/help or opinions are greatly appreciated. Thanks in advance

if your filter is open or the box you will be able to hear the intake such as mine if a romp on it i can hear it sucking and if i let off quick you can hear it "despooling" or the woosh sound. the box is kind of like a muffler so when you take it off you can hear it. i wouldnt worry about anything just hearing ya motor work

Totally normal for these trucks.

Thanks for the info. Next step is a turbo back 4" exhaust. I've owned the truck for less than a year and am making upgrades as money becomes available. Unless I get tunes or programmer should I be concerned about EGT's with the factory/stock "tuning"? Just curious. Thanks

Not really, unless you are running it really hard. I would recomend getting some gauges, specifically EGT and transmission temp. Definately get the gauges BEFORE the chip/programmer.
