MORE HP AND MPG

i pull hopper with t600 t660 and aero style petes and they don't get any better milage than my long hood today a 1 mpg advantage would make your truck payment if a t660 got 1mpg or better than a 379 there wouldn't be any 379 on the road all i was wondering is if any one has had any luck tuning there trucks wint aftermarket kits or add ons

Your right if the aero trucks are 04 or newer, dead wrong if not. 1 mpg difference unless you drive 55-60.

As the other post recommended..contact pittsburg power...They will recommend a variety of things..depending on your pocket book...Also put a timer to shut off the engine after 3 minutes...idling kills fuel economy..and shut off the truck with an APU...it is really surprizing how much idle time you have.I was at about 47% without my apu ,it will be a real shocker...When I was pulling heavy..I found .the different fuel companies have different grades of fuel...Yeah Flying J is cheaper...but I found that TA and Petro has the best for economy...Also put in Howes every couple of loads...even in the summer...It lowers your cetane and helps lubricate the upper parts of your engine...The Best fuel that I found was at National truckstop in Vada New Mexico.And the worst was any Flying J...The power just wasn't there....As before look into one of those FASS filter set ups...it takes the air out of the fuel..so you get a full burn...It is surprising how much air the fuel holds today...with the return of the fuel from the engine..it cools the computer on most engines...Also with Bio diesel...it just depends who blends it and what the percentage is...Found Sapps was one of the better...And as other have said slow down..to at least 65....Also the tires and air preasure is also criticle...10 lbs off and you have drag....another is is your trailer going straight down the road?? might be a dry 5th wheel..another drag and tire eater..or look into wide tracks...We can all go on and on about improving your mpg...But if the freight paid what it should...you can afford to pay for fuel...even at 1.20 a gallon..you need to try to get good fuel econony..as it is pocket money...Why is it that the old pre 80's engine averaged 5 miles to the gallon...even before all this crap that they are doing now?

Don't waste you time or money the air cell or fuelcell 3000 we put one on one of our trucks with a C15 Cat and it gets the worse mpg in our fleet around 5.5 I personaly drive a 99 W900 with a 550 Cat and get 6.5 mpg loaded and almost 7. empty pully an insulated tank... We also have 4 trucks with C12 and C13's and all them to seem to be averaging around the same 6.5 to7.5 mpg.....I'm thinking of replacing the C15 with a C12 in my one truck since its has almost 950000 on it, it seems to running fine now but its day is coming plus I would love to get rid of some of the xtra weight..it almost 20500lbs now and I think I could drop 1500lbs on it...good luck

i have a 96 pete 379 with the 3406 e and i get around 7 mpg but i have 18 double over with 308 rear end if you can get you rpms down to where they would be at around 55 you will get the best fuel milage at 70 to 75 thats the only way i could get the mpg to be up you dont need a new truck just fine tune it

How is a 3406E model turned in to a B model? Just curious....

thats all i did but i have a friend that works for dean cat in kansas city that set the pump and tweaked on the turbo for air thats why my truck is turned up and is a manual motor but still gets good mileage old trucks and old cats set up right are hard to beat but thats just my 2 cents

Why would you want to? No way a B model is as fuel efficient as a well tuned E model. At least not in my experience, and I've owned both.

The first E models they had tons of problems..I had one....bad cams..replaced twice..bad computer plugs...This is the major problem..water could get into the plug in and short out the signal or rust the pins...but to go back to a mechanical pump??? wait until you get smoke checked...Think of this...all of that black smoke is unburned fuel...At the time that the first E models came out CAT was on strike with replacement workers ..that really didn't know what they were doing...I had 1 o ring on a plug for my jake missing..the one going to my computer was nicked bad enough that it was letting in moisture and shorting out the signal...And than there was the idiot..that thought that CAT could save a buck and had outsourced the cam shafts...the lobes would flake off...Have you ever replaced that...The first sign is the engine stutters or runs a little rough...And what about all the other electronic sensors???

Set us straight by giving the engine serial number, or, at least the first three characters. I don't mean any disrespect, just curious.

you might even want to look into a super 10 for trans. they are even a little lighter than a 13 and really don't shift much differently. the only difference is you split every gear.
