Started my truck up today, havent drove it in a few days. It was about about 30 degrees out, not plugged in, It started ok and everything but i noticed when i drove it that the EBPV was kickin in. This is the first winter im gonna have with my PSD, and i was just wondering if its normal for the EBPV to kick in, and when it does, does it go on then off again, then on. And for how long does it do that, i let it idle for probably 5 minutes and drove it for another 15 and it was still kicking in. Is that normal? Or did all of you take yours off? Im thinking thats what im gonna do, seems like it never helped a bit, just annoyed the heck outa me.
Another thing my truck never reaches the N on the Normal label on the temp gauge, is that normal also?
Thanks
I would unplug it, see if you miss it. I don't. It's the plug in on the compressor side of the turbo. It is attached to the side, the wires come underneath where the intake pipe clamps to the turbo. Just unplug it. It will set a code but not turn the check engine light on.
you can also pick up a sensor eliminator from one of our sponsors that will prevent that code from being thrown.
It is normal for the EBV to open and close normally during cold weather startup and driving. You will notice that it will quit fluctuating once the engine warms up. :chicken:
Does anyone have a removal sheet or a detailed step by step perceedure on removing this. I am ok with doing work but I just need detail instruction to make sure I do it right.
I unpluged mine this morning and I noticed a slight power increase even when cold. I think this is normal. With this being unpluged should I still try to remove the flap or gate that is in the inside of the exhaust side of the turbo? My concerns is that I have herd of people doing this and then something happens to the linkage and oil goes every wair. Thanks
I removed mine, with no problems. I have a 99 though. Someone are here said the older ones 97 and earlier have more of a problem with them leaking though. When you remove the turbo to do the valve you can take the linkage apart and plug it off. If you search some of the older threads about this there is a link that describes how to plug it off. You will get better exhaust flow with it out of there. Since with it in there the exhaust cannot continue to spin out of the turbine. It can only make about half a turn then it hits the valve causing turbulance in the exhaust. I have remove one on a 96 about a year and half ago and have not heard of any oil leaks from him.
didn't notice that much, but mine spools quicker than yours since i have a waste gated turbo. The most difference I noticed on turbo lag was when i installed a wicked wheel.
When I gutted mine I also plugged the pedistal, but I didn't really notice any less lagg. You do kinda get a woosh sound during shifts though that isnt there with the valve present. I have found that a good cure for lag is MORE FUEL!!! Besides the sound difference I also had around 75 degree egt drop so that was a plus, I thought the difference would be nominal.
I got the fuel now, was just hoping to get the boost up a little faster in low RPM
Any actual performance gains noted without the flap there?
