Can anyone tell me how to bypass the exhaust backpreassure valve on my buddies 1999 7.3L F-250 or provide a link to an existing post. Any help would be greatly appreciated. thanks

Just unplug it. If you climb up on the top, look down right in front of the turbo, on the pedistal there is a wire connector, unplug it. This will keep it from activating, it will set a code, but it will NOT turn on the check engine light.

Thanks I wasn't sure if it needed to be powered to keep it open or if it is open when there isn't power to it. You guys are very helpfull thanks to everyone that replies to those of us who are just learning.

What exactly is the benefit to doing this and are there any negatives to it?

The exhaust back pressure valve is a butterfly valve on the backside of your turbo. It is strictly to aid your engine in warm up. When its cold out your pcm will close the valve to help warm the engine and you will hear a hiss out the tailpipe. The downside to this is it can stick and not open or not open all the way and it has a negative effect on gas milage. When your truck is off unhook your neg battery cables and look at the front base of your turbo pedistal is a two wire plug that has a wire clip to hold the plug from comming loose. Unclip the wire clip and unplug. This will cause a code to be stored but no ses light or adverse effects. In fact it was the best mod I did untill I gutted the whole thing this past weekend

I unplugged the plug that is almost dead center of the engine at the front of the turbo, at the bottom of the housing. Is this the one we are speaking of? I did notice my boost was quicker to respond and it would climb to 21 to 26 lbs quick when you stood on the throttle. That was faster response than what I had been experiencing. Sound right to you? Thanks again!

Yep its the two wire plug that plugs into the solenoid on the front of the turbo pedestal. It could have been sticking partially closed on ya before.
