New Turbo - MPG's Dropped

I had a new Garrett Powermax turbo installed a few months ago and since then my MPG's have dropped by 2-3. The weather turned cold shortly after it was installed so I thought that this turbo just hates the cold so I installed a FIA grille cover but that didn't seem to make any difference in MPG's. Truck is an 05 F250. All stock except for a BPD EGR cooler and a coolant filter. I took a ~900 mile trip over Christmas and only once did I get normal fuel mileage, ~16-17, and that was going a steady 60MPH. I don't drive like an *** and I keep the RPM's around 2k when accelerating and the only thing that has changed was the new turbo. I thought maybe a fuel filter so I changed both and they looked fine. Only thing I noticed was the one underneath the drivers side door was hard to get out and the new one the same to put in. I had thought I just did it by hand the first time I changed them but I needed the ratchet most of the way this time. EGR valve was cleaned last summer when I replaced the oil cooler and all that. I'm really thinking about putting the stock turbo back in. I can't afford to drive this thing at 8MPG

Winter fuel is probably the culprit. It may also be the tune you are using. Just putting on a turbo like the PMax without making any adjustments could reduce your economy.

I'd say it's the fact that you don't have specific tuning for the powermax. Try getting a custom tune and see how it does.

I figured I would have to get it tuned, just didn't want to spend another ~$500-$600 to get it working. Will have to keep an eye out on eBay for a SCT X3 3000. I sent an email awhile ago to Innovative Diesel asking about their tunes. I was looking at their Xtreme Street, Street, and Tow. I do need to ask them if/how much I could tow with the Xtreme Street tune. Hopefully my MPG's will come back as the weather warms up and I can look into getting it tuned.

I now know that cold weather effects the fuel mileage big time. Last summer I pulled my 15000 pound RV and got 12 MPG + or - a little. On Jan 4 I left Illinois headed for Central Texas, that 900 miles I averaged 9.0 mpg. I had lots of side wind and some tail wind but never head winds. the temperature ranged 20-50 degrees. When it was below freezing the mileage 8 to 9 mpg. There was period of 50 degree but as cooled 30 degrees I watched the average drop from 12 to 9 MPG and was all in a couple hours on the same tank of fuel. The boost run close to 20psig when the fuel mileage was less than 10 mpg.

Winter fuel will drop mpg no doubt. But you can't expect to get a way bigger turbo then not expect to get the tunes that are needed to make it efficient. You'll get better mpg, efficiency and driveability. It's worth it

^^^^^This^^^^^

You're going to have to tune it. Get a tune specifically for the PMax. A billet wheel will help too, but not with mileage. The billet wheel will help with spool up and dead spots you'll encounter while towing. You'll have to drive the truck tuned all the time. The stock file isn't gonna cut it.

At MAD TURBO WERKS, we deal with this constantly. We have recently teamed with PHP to offer their tuning with our turbos got optimal performance.

For me a billet wheel not only helped with spool up, it helped city mileage some as well due to the decreased effort in spooling.

Yep, what others have said, regardless of what the sales guy told you, there is no bolt in or on aftermarket Turbo. 2005's are the hardest to tune but Eric can and will take care of you. There are others out there too that can tune these trucks with a P-Max.

If you wonder where your 2 -3 MPG's have gone just look in your rear view mirror, or the passenger mirror down low. Smoke = Badddddd
