Poor Fuel Milage upgrade

My 1996 7.3 dually with 106K miles gets 8.2 MPG when towing my car trailer. I must do better. Love my truck and do not want to trade or sell. I'm told that an upgrade to Banks or equivalent 4" exhaust, a better air intake system and a "tuner" will bring the MPG to 12-15. I'm not sure what any of this is. Any help from you guys would sure be appreciated.

Thanks so much,

buickman

Poor Fuel Milage upgrade

Yep all of that should significantly increase mileage and power. The stock exhaust on an obs truck is very restrictive so changing it to a more free flowing one will do wonders. Same goes for the intake. Do some searching around and you'll find tons of info on the subject.

I'm looking as we speak. I wonder if there are specific references to good one's and bad one's. For example, I saw 10 different tuners offered - tough to know which one is the most reliable etc. Same for exhaust.
thanks for the help!!!!!

Doesn't have to be a fancy brand name exhaust. Get an after market two piece downpipe (factory is squished almost flat, poor design) cut out your cat and muffler, build a diy intake using a piece of pvc and a 6631 filter, ts6 chip with tunes from TW, Beans, whoever...there are lots of guys writing good tunes.

Those few things and you will see a big improvement.

Stay away from canned generic tunes (superchip, edge, bullydog, etc). Custom tunes with a switcher is best. Php, tw, dp, beans are all highly recommended.

For exhaust they're all pretty much the same. Just get one with a two piece downpipe. MUCH easier to install.

My first upgrade was a full Banks setup. But like JJ said it is probably the most expensive way to go. I don't have a Dually but I was getting 24 MPGs unloaded and 15 with a three horse trailer with living quarters 12,000+lbs (your numbers will be a bit lower with the added rolling weight and tire/road friction). Loved every minute of the Banks system.........................until I wanted more.

If you think that this is all that you will need for years to come then I say spend the money on the Banks Power Pack system. It has everything from the full big exhaust (get the added muffler delete pipe, about $45) to the chip to the 1.0 turbine housing to the trans controller to the InterCooler. The air cleaner is junk. RiffRaff for that or make your own. I pulled for years with this system and never had a tranny issue till after I took it off.

IF, you are thinking more power then that buy it in pieces and buy more then you need. If you are looking at only Stage I injectors get Stage II's and tune them down. Same with most anything. Getting just enough WILL leave you wanting more. Just my

You guys are the best. I just ordered the exhaust from Amazon. It will arrive in mid to late February. Now for the air intake system. Any advise is greatly appreciated.
Thanks so much

You can spend big bucks on a brand name air intake like AFE (what I have cause I bought it before I learned more on here) or you can seriously just get a 6631 filter from NAPA or wherever and piece of PVC or whatever kind of piping you want for a fraction of the cost of brand name. Pretty much everyone here has a DIY intake.
