so does theebpv switch is it noticably when towing, and how do i do the bb mod when i did a search on here it seem to be doing the 6.0. what you have done seems close to whati want till i win the lottery (haha) im not trying to go ape **** like some guys runnign 800hp. your down pipe is =it the diamond eye one i looked it up and it is a two pc because i tried to remove mine and it seemed with the bodyy on i will have to cut to remove. oh with your monds whats your mpg average?

 

I have the diamond eye 3" downpipe (2 piece). Easy to install. Getting the old one out is the hard part. You have to cut the "head" off near the turbo and cut it as far up as you can from the bottom as well. Then just need to cut and bend up the seam on the firewall.

For the FPR shim find the big brass nut on the FPR (driver side of the fuel bowl). Remove the nut and the spring inside. Place the BB inside followed by the spring and nut making sure the spring is centered on the nut.

I average 17-18 mpg mixed driving. Over 20 on the highway.

 

i think im goign to go with the same mods as you. i forgot you have a higher gear than i do i would change but i never know what i might want to haul so for now im sticking with the 4.10. so does your homemade jake brake work good

 

I don't have the homemade jake brake on mine. I've heard it can wear out the coast clutches on automatics.

When I bought mine it was a dually with 4.10's and I averaged about 15mpg completely stock except for a 6637 intake.

 

sorry i didnt mean it that wahy i ment the evbp switch

 

I would personally not recommend the ebpv brake. It is somewhat effective, but I believe the extra strokes in and out of the pedastal can cause premature turbo problems (leaks,cracks)

The truck in my sig. gets 20.5mpg at 62mph on the interstate, around town I get 18-19mpg. and If I drive with my foot in it it will drop to around 16.

The worst towing milage I have gotten was about 17mpg, this was a total weight of 16,000 lbs.

I bought my downpipe from 1994-97 7.3L Ford Powerstroke Chip Programmers Tuners Engine Components Gauges & Mounting Accessories
It is Diamond Eye and I got the stainless one and have been very pleased with it, the only thing I had to do to get the turbo outlet and the pipe to seal was to crimp the bands on the clamp.

 

I am getting ready to gut the EBPV if that tells you anything.
It hasn't ruined my tranny, but its not stock.
It helps some with slowing down, but honestly I'd rather have the quicker spool and wicked turbo whistle, lol. Oh and slightly lower egt's.
But for about $6 dollars, you can't really go wrong,

Oh yeah, you get more of a hissing sound, not what you hear on a semi.

I get about 18.5 mpg, and I drive my truck for all its worth.
Towing, lowest I've seen is 15 mpg, same driving style.

 

ok have an update on the truck well called ford there commercial branch and talked to tech and he said 90 to reflash 110 to throughly scan and check presures while running and so forth asked what it was doing and told him he said it might need an update or more to dianose and update worst case nothing mechanical 190. in the mean time i notice no power barely climbed aroot in front yard that ive done tons of times almost got run over in traffic the other day and most of all no turbo wishel before i had it at idle so i reprogramed and yep smelled rich but i have a wishel and seems to have power again will drive later. also i notice while stock the ebpv moved a start then emmidiatly moved back. did not watch to night was dark.

 

hey brown i read the post on the 3" dp and i know you dave to mod the cab a bit with your 2 pc did you still have to mod. i have a porta power the harbour fright one so im prepared if need be

 

It was $35 for a reflash for me ???
Two updates included.

Here's a guarantee: Have Ford do the tests, they will tell you that you have two bad injectors. so you fix them, they rescan, and "oh my! you have two more bad injectors. you might just want to replace them all."

 

i wouldnt be surprised if they said that but one thing i like bout a stroke verses a cummins i can run them till the go out with out hurting ther others. i guy i know had a bad injector inhis didnt replace when told to due to pressure problems because of bad one not pulling its own weight he screwed three more in teh prosess

 

I did have to bend up the seam, but that's all. I didn't have to do anything major to the firewall.

 

ok cool. when i first got her i looked into it and the mufflur shop i had to bend the firewall so i didnt get one thanks once ti get the deprogrammed major power loss fixed thats the next step

 

It really depends on the individual truck. Some seem to have the cab mounted farther forward, some farther back. Mine was easy to get in, some need a little more work on the firewall.
