Finally decent mpg!!!

[walleye guy]

Hello and Happy Holidays! Well, I finally got some good mpg with my 99. I had been getting around 12 to 13 on a trip. Thats until I wired open my wastegate. On a trip to my in-laws for x-mas, I got 20.5 mpg!!!!! Hand calculated. I have the superchips on performance, 4" exhaust and a k and n cold air intake.

Open?? So u didnt build any boost? Anyone else done this? Id be willing to try it for a road trip if it gives noticable gains.

Waste gate or EBPV? Good mileage though.

I think you mean the EBPV. It does restrict your exhaust slightly even when fully open. Apparently, it was not working properly because it should alway be open except on a cold engine during warm up.

Take Pictures of the way you wired it up!

I had brought my truck into the local Ford garage to get it scanned. They told me the wastegate or egpbvxyz or whatever you call it was gummed up and that the solonoid on the pedistal was bad. told me $900.00 to replace. Then I had posted on here about the problem. The replies told me to just wire open the wastegate? So I took off the arm from the solinoid and also unplugged the solinoid. Then opened the valve and wired it so it would stay open. The way I understood it was that by keeping the valve open it would just take longer for the truck to heat up??? I'm not mechanical, all I did was do what I was told. On the tank before I opened up the valve, I only got 8.5 mpg. After I opened it, 20.5 Just to clarify... the part that I'm talking about is the buterfly valve that is located at the mouth of the turbo. I will take a pic and post it.

That is the EBPV - otherwise known as the exhaust back pressure valve

little buggers kill mileage when they close!

[cowboyupamrka]

i wonder if that might be part of my problem. not that bad on mileage but not that great eithr and it used to get a lot better. i will check into that

[rajharley]

me wanna see pics too. or at least a piagram pic with pointers showing me what to wire open. Can the butterfly valve be just removed all together? Or am I getting crazy?

do a search for "ebpv delete" there have been multiple threads about it, how to remeve it, where to tap andplug the actuator piston and how to remove the flap and plug the holes.
