deleting the butterfly valve wont do anything for your power unless the valve isnt operating properly. If the valve is open going down the road like it should be it is such a minute restriction that you wouldnt even be able to measure the difference on a dyno. The only thing the valve does is to cause a bunch of backpressure at idle helping the motor to work harder and heat up faster.....

yah it comes on when drivin down the road at a steddy pace. Its loud! And i was told its only suppose to be on in the driveway at idle

unplug the ebpv. Its the two wire connector just underneath and foward of the turbo...drivers side. The truck just won't heat up as quick. Mine was doing the samething, closing going down the road. Sooner or later, I'll get around to changing the sensor, when i decide to do the dyi engine brake.

was yours loud to?

YES, it was extremly noticable, sound and loss of power. I could really hear it good since My exhaust consists of a 3" down pipe into a 4" pipe that extends only 1' under the bed. It used to only do it every once in awhile, after leaving the driveway. The night it started actting up, I drove it about 15 miles. After being in wal mart for an hour or so,and the engine cooling, I unplugged it. No more problems. Do a search for "EBPV" or "Bad EBPV". One of them has a pic of the connector. Keep us informed on what you do and think,

search it on the board? Did you notice anything after unpluggin it, good or bad

[CHUCK]

Yea, search the foroum page. Other than it not operating and closing going down the road. It does take a few extra minutes for the cab to get any good heat. But, nothing I'd consider bad. i read somewhere, that some people picked up a few mpg, I havent though.
It will set an engine code, the c.e.l. wont come on, its just stored and will show up if you have the codes pulled. I saw a thing on ebay to plug into the connector, so it dosent set a code, if you wanted to go that far with it. Its made by SP diesel.

I live in St George and mine comes on driving down the road all the time. It usually goes off after about 5 minutes of the truck being fully warmed. I have yet to unplug mine but I have no exhaust so it is extremely loud. My exhausts exits under my passenger floorboard.

You a Police Officer?

You can put a switch to it and get your fast worm up and even use it as exhaust brake if you want. There is a post on how to hook it to the fuel and brake peddles so it works like a big truck. To me the switch is fine, only on when I want it. I turn it on when I park the truck so if someone swipes it they wont be going very fast if they don't turn it off.
