Well, now what should I do??

Started with an 01 7.3 cclb with 4 speed auto. I have taken your advice and done the following mods:

- Complete 5" lift with upgraded shocks
- New up pipes with flexible bellows
- New 4" downpipe and complete diamondeye exhaust
- 6637 filter
- Wicked wheel
- unhooked EBPV, tack welded turbo valve open, removed guts and sealed
- PHP Hydra
- Helo 16s with Nitto Trail 315s
- New moog ball joints and bearings
- EGT, Trans temp and Boost gauges
- 15psi boost fooler mod
- Installed 08 rear diff cover
- Changed oil, diff fluids, hydro boost atf, brake fluid, transfer case atf, etc.
- Working on hutch and harpoon mod tonight

I am disappointed that my mileage has went down so much. Also, the power is not that great. I sold my duramax LBZ with about 400hp and it was amazing. This truck is far from making my smile yet, from a power point of view. I'm also a little worried about the tranny(4eod auto). When I serviced it, there was a half teaspoon of what looked like finger nail clipping size flecks of metal.

What should I do next??

What did you do that would make you think your mileage would go up?

MPG no no's...

1. Lift- Check
2. Big tires- Check
3. ?15psi regulator mod?

First off remove your "regulator mod" and install one that allows at least 20psi, or your leaving far too much on the table.

You also have a 4R100 trans, not an E4od...

Your mistaken. The OP has turned his truck into a great big brick moving down the road.

Also he would be lucky to dyno 300hp, has really done nothing more then chip it as far as power adding.

I do not have my boost gauge hooked up yet. I will get it hooked up tomorrow and get you a reading.

330hp??? It seems to act like a dog when accelerating. I need to check on my fuel pressure under load too, but I will see how it acts when the hutch and harpoon(not that it matters) mods are done tomorrow.

Fuel pressure will not effect hp so long as your filling the injector, 60-72psi...

Large chunks should never be in your tranny pan. That's not a good sign at all, and you should probably start saving for a new trans.

As for mileage, I agree with CSIPSD. You took a brick, and made it bigger. What numbers were you seeing now, what were you seeing before?

I don't know about 330, but you should definitely be over 300 with just the chip. I'm at 310 on PHP's 65DD tune.

The "Wicked Wheel" likely lowered your max boost, and you shouldn't have gone with it unless you were experiencing turbo surge.

How thick is your smoke trail when you get on it? If it looks like a Cummins, I would venture to say you have a boost or exhaust leak somewhere and that would be a large contributor to unexpected mpg losses.

Gauges are a must. I love my Edge CTS, as I can monitor so many different things in a nice little package. If that's not your thing, you need several gauges, and a good scanner such as AE. The CTS isn't a replacement for a proper scan tool, but it does provide monitors for things you won't get a gauge to do.

The computer when it was stock, driving it home from oregon, was 19-20. As for now, I get about 13 on the freeway. That seems HORRIBLE to me. I got 7.8 towing a 5k trailer today on the freeway. I guess I better check all the exhaust connections since I just redid the up and down pipes.

i understand that lifting your truck is gonna kill mileage. but i was just looking at other factors, that one is obvious.

their is a ton of factors affecting mileage. so you pretty much have to go down the checklist. boost leaks, fuel pressure, oil pressure are easy to check.

and i agree about the gen 1 ww wicked wheel, when i put one om my truck it killed my top end power, and mileage went down as well. bu i didnt have surge anymore so your better off getting one of the newer billet wheels.


and i guess i did overestimate is hp #'s

i just sold my old wicked wheel to a gentleman the other day who told me he gets 30 mpg in 99 f250 6 speed because of is HHO converter

Your going by the overhead?

Forget about the overhead for MPG discussions. Its 100% useless.
