Turbo boost relief?????

Not so much a problem just bein curious. When I start my truck when its cold it runs fine for about ten seconds then it starts letting pressure out of the turbo. It lasts for about ten seconds then it just stops. Ive driven others the same stile and year that do not do this.. Is this a problem I should be concerned about?

Loud hissing sound out the exhaust?



If so that's normal, that's just the EBPV cycling.

Yep, totally normal. Most just unplug it or gut it.

It's there to aid the engine warm up...

You know, I never understood how there was no noticeable difference when I had it plugged in or unplugged.

How did you set up your test and what were your variables?

Re: Turbo boost relief?????

I guess I'm more basing it off the fact that it took the same amount of time for engine oil temp warm up (forget what number I had the alert set at) after sitting unplugged over night when it was in the mid teens. Took the same amount of time to get warm heat.

Not a real scientific test but I would let it idle and warm up the same amount of time after starting it 5:45 am and leaving at 6am. Took me about 10 mins to make my lunch, spent the next five in the truck.

Not gonna argue with you... But I have to assume Ford's experiments didn't include a variable called "about 10 minutes to make lunch"...

It's there for the reason I stated, if you don't want it to do it's job, unplug it. Simple as that.

Re: Turbo boost relief?????

Oh trust me I believe it's there for a reason. Didn't mean to make it come off as your wrong or anything like that, just more stating I didn't see any noticeable difference with it operating and with disabled.
