Ok, so here's the deal. I took my truck on a 1200 mile round trip to see family for thanksgiving, and on the way there the truck ran great. I averaged 19.67 MPG, but I was empty and not pulling a trailer. So then on the way back I was pulling a 24 foot flatbed trailer hauling a steel flatbed that I am going to put on my truck (weighs a couple hundred pounds). The truck had no power and got 10.32 MPG on the return trip. Also the ABS and BRAKE lights are now on and when I rev above 2300 RPM's I can hear a hissing noise from behind the dash, it sounds like it is comming from right behind the airbag on/off switch area, but it is hard to tell for sure (also it makes this noise even in neutral revving the engine).I also noticed that I was getting no black smoke at all, not even when I would go into a long hill and push the throttle all the way, it almost feels like I don't have any throttle after 3/4. I was having to down shift, and barely dragging over the top at 45-50 on hills that I usually pull in 5th at 70-75. So I stopped and looked things over and found nothing obvious wrong, so I unhooked my van aken chip to see if that changed anything, it didn't seem to make any difference, actually maybe a little less power if anything.At first I thought that I wasn't getting any boost pressure (I don't have a gauge on it), but if that is the case I should have black smoke. It feels like it isn't getting enough fuel maybe.Any ideas of what I should be looking at would be greatly appreciated, because I have to take it again this weekend on a snowmobiling trip.Thanks in advance Oh, I also pulled the codes and only got a P1693 code, I can't get the cheap code reader that I borrowed to show the companion codes that would go along with the P1693 code.

Changed out vp44 a while back and cant belive the fuel mileage increse.Went from 15 mpg to 18mpg,truck is heavy 9900LBS

I going to install some rv 275 injectors in the near future. Also a j- hook, but what kind of boost fooler ( diablo power puck ) not wanting to spend $1000.00 on edge. I may trade the truck in 2-3 years for newer.

so i was doing some thinking today on my way home since i started driving 65 rather than 70if i can gain 2mpg by doing 65 rather than 70 mph i will save (fuel at $4/gal) 3 cents a milei will use my situation.. Drive: 70 miles/day 20 days/month 1400 miles/month x .03 cents = $42now saving $42 a month doesn't seem like much but lets look at how much more time it takes for me to drive 70 miles a day at 65mph vs 70mph60min/70 = .857143 minutes/mile x 70 miles = 60 minutes of driving per day60min/65 = .923077 minutes/mile x 70 miles = 64.6 minutes a dayso if i save myself 5 minutes round trip thats 2.5 minutes per one way so really unnoticeable as far as fuel savings by driving slower and time savings by driving faster (5 minutes versus $2)heres where it gets interesting... if i look at that as dollars an hour i can take (2x12)/(5x12) = $24/60min:smart:so by driving 65 miles an hour rather than 70 if i look at it as time spent for the money saved im making 24 dollars an hour just for driving 5 mph slower...what a deal!also..im in the process of checking my exact mileage gains but say i get 4mpg more then everything doubles+2mpg = $24/hr+3mpg = $36/hr+4mpg = $48/hrnow as fuel prices go up... so does your money making!!:cookoo:i always like to look at the positive side of things:thumb1:

I am a newbie here but I have been reading for several days and most everyone can only get maybe 18-20 mpg out of a 24v. Trying to figure out how my truck gets such good mileage. Can get 24+ with a steel Knaphiede bedcover that wieghs 1200#. I AM NOT COMPLAINING!!!!!! Just trying to figure this out... No electronics on truck. tires 245/75-16LT 3.55 auto

ok....I know I'm running a lifted truck with 315 tires and 4:10 gears but doesnt 13mpg still sound really bad? 120 miles of the 200 i just drove was highway at 57 mph. the rest was in city and some extended idling for warm up before driving. also, my exhaust manifold is cracked...but I don't know how much this would affect it. What do ya think?

Took my truck and trailer (trailer rated for 14000kg) and drove 3.5 hours to pick up a backhoe attachment, drove back. Filled up and checked my mileage and was very dissapointed to see the result! 11.6 mpg

Alright Mike, not trying to prove you wrong but I want to figure this out.You say cold IAT drop MPG big time on yours.You say Winter Fuel drops it.So why is it that running winter fuel with no winter front whatsoever at 25F ambient at 70mph, do I get the same 21mpg (actually 21.54mpg) that I get on a 100F day? I get consistent mileage all year, summer or winter fuel, rain snow sleet or hail. I know everyone here seems to have this "it's winter fuel, so it's ok to see 2mpg loss" but why am I not seeing this loss! I am thinking if I could figure this out, I could help you all not get a loss either.

$3.29 per gallon at my usual fiiling station. time to run 10% waste oil..Ops

i have a coworker that has a 07 3500 that is bone stock. he has just under 100k miles. he was complaining that he gets real poor fuel mileage. he said his best tank ever was 14MPG but is usually 10-12 empty and ~8 when pulling his cattle. he said that it doesn't have the power it did new. he was thinking about buying a used bully dog programmer. i warned him that he needs a EGT gauge before he starts adding fueling enhancers. i also suggested a compression test.also his tires were "loosing" lugs on the inside of the tread face. they were a Hankook off-road tire. i thought it was because using a off-road tire on the highway, but it was only the inside lugs. like every other one was finedoes anyone know of anything i can tell this guy?

She runs like you anit never seen, boys I am going to be hitting 19 mpg I just know it for a 9800 lbs truck. It runs so smooth you dont even know it's running, sounds like a electric car it's so quiet. 2 Years of misery man finally over, next I be hittin the rollers LOL.Sorry for all the excitement, I just cant get over it's finally done. 1 Million miles here I come. Well only 750k left to go.

What MPG to you 3rd Gener's get on the CR - must tow more than 7500 lbs And be HAND CALCULATED !

Topped it off today and I thought it would only be 10mpg based on how I was driving. There were several long steep hills lasting maybe 1/2-3/4 of a mile and I would hold it at 65-70. I went that fast the entire way there and back. The A/C was also on full blast for the duration of the trip. That should have yielded me about 21-22mpg unloaded. This tank was with the trailer on it the whole time, did a lot of miles around jefferson city to go shopping (sisters bday). Ended up being right at 500.6 miles at the gas station and 29.013 gallons means 17.25 mpg. Sooo I'm very amazed. The trailer only weighs about 4000 but the billboard effect really loads it down. I had a quart of 2 stroke in that tank. http://forum.mopar1973man.com/attachment.php?attachmentid=210

My mileage is normally ~16 all around hwy & some city. Yesterday @ 70mph on the interstate the overhead said 16.4. Overhead on my truck is usually close to hand calculated. Regardless. I want more. I have a new SO MWFI VP.Let's start with making sure we're up to spec then mod. What get out of adjustment or wears & reduces mileage? Will start by checking:adjusting valves, cleaning IAT & MAP sensors
