ya 5" exhaust on a stock truck is big time overkill. you might tell yuor buddy to look at dptuner website he could really wake that truck up if he wanted to.  

thanks ill let him know hes thinking about scrapping the whole exhaust and getiing a banks kit im not a big fan of banks prices for the performance that they give you and ive heard alot of people say they arent much better than some of the other stuff and they are expensive but he wont listen to me im trying to get him to come ask his own ? on here  

i can tell you from my experience with banks dont do it. it will be a headache and yes they are WAY overpriced. he can use the money he saves on important things like DIESEL FUEL.  the only thing i would purchase from banks is the technicooler thats it. afe intake, mbrp ex.(no cat no muffler provided yuo dont live in a state where they do emmisions checks.) dp tuner files, and his truck will be rolling  

Yep. They do make good intercoolers. But their stuff is a little on the pricey side.  

and tuned way low on the safe side. there are better products that put out better power that are cheaper.  

I put the predator in and set tow mode. went out this weekend. 28' toyhauler and two four wheeers along with 150 gal of water, etc. Before the predator, i got 7mpg with this. withthe predator, it went up to 8.5mpg. Now to do the air system. Anyway, I was impressed.  

sounds good man just dont forget about the xhaust when you get the air intake.  

Yea. there is a new powerstroke place here in Anchorage. Gonna check them out...  

Got 16 mpg with a full load on the 6.7 this last weekend. 06 got 18.9 last week and the 12v was the big loser and got 11mpg. Oh almost forgot.... The Jeep got 38mpg too.  

My 99 Dodge 2500 gets around 22 as a daily driver if I drive it easy.  Where I live would be considered mostly highway.  Use the cruise control alot.  My boss has an 07 Chevy 2500 LMM crew cab with a long bed and he gets like 16 towin a 6,000 pound trailer around all the time.  

16 towing isn't too bad. Shoot, from what I've heard, that's better than what those new 6.4 Power Strokes are getting unloaded!  

at least ford circled the problem  

Took my truck to Florida a few weeks ago. Before we left on the trip, I did the "filler vent re-location mod" on the fuel tank, which brought my fuel capacity to just a tick under 40 gallons. (If you want to know more about this mod, click here:  http://www.innertruck.com/store-products-Longbedfueltankventkit-Long-Bed-Fuel-Tank-Vent-Kit_23095779.html    
                 
We filled up on the south side of Atlanta, GA and made it all the way to Columbus, OH before the idiot light came on. 809 miles total, including a 100 mile jaunt in 5th gear at 35mph on the Blue Ridge Parkway in North Carolina.

Took 36.7 gallons to fill 'er back to the brim. That equates to 22 MPG. May have done a bit better if not for the Blue Ridge, but that was worth it. Not too bad for an 8000 lb 4x4 with 4.10 gearing.  

I just bought my first diesel. A 2008 6.4L powerstroke. So far with 8000 miles on it I get 14 mpg. I am listening to all of you from Houston,Tx. I would like to do some mild mods such as air intake, exhaust, programmer. I was leaning towards Banks but i am open to suggestions from people with experience.  

there arent many mild mods for these new engines you can do an intake and dpf back exhaust some companys makes dpf deletes and programmers for the truck but from what i heard is that it will blow the motor.
