thanks for backing me colorado bill, the toy hauler we just bought was empty and when we fill it it will be somewhere around 10600 , so my queastion to those who " have these extraordinary trucks" what do you have done to them or is it just the ego?

 

Just bought my 2nd ToyHauler (28ft TT) and it's weighing in at 11,400 without 100 gal water yet. I basically am stock other than filter and intake tube and Yeah it feels heavy back there. BUT where are you going to get something that can still pull the hills at 50mph+ and get 12mpg+ and last 300K miles until the next rebuild. Had an Expedition all modded up pulling a 21T Toy hauler at 7K #'s and got 8 mpg at best and did only 35-40 pushing it on the big hills.
You will find alot of the ones pulling the 12-14K'rs have put a programmer or chip to better there towing and mpg though IMO.

I have 5200 miles and have yet to be able to chirp off the tires.

 

I am wondering if there is some sort of programing in these that effectively has them turned down until XX,XXX miles? Then they change the fueling curves in the puter and they run/pull better.

 

Well oneslowyfz, you gotta remember that your version of pulling easy is different than someone else's version. Joe Pullsalot that pulls 18,000 pounds for 500 miles each day is gonna tell you that pulling 6000 pounds is nothing and his truck does it with ease. However, Joe Nevertow that pulls a snowmobile trailer to Michigan once a year is gonna tell you that he can really notice a trailer back there. There's just too many variables to be comparing yours to theirs. You don't know if they have 200+ HP worth of add-ons on their rig. Your is just fine, and if you just get too fed up with it, I can give you my address and you can drop it at my front door.

 

I regularly tow my trailer (14x7 box trailer, 5500# or so), and I sometimes forget it's back there. The day I bought the truck, I put it in the dyno, then installed the Quad box in my sig and ran it on the dyno again. The next day, I towed the trailer to Kentucky, about 1000 miles one way, and then back a few days later. I didn't try to smoke the tires until I got back from my trip, but when I did, I smoked them in 2nd and 3rd, and chirping them in 4th and almost in 5th. (I launch in 2nd pretty much all the time, L is way too low.) With the Quad box, I put out just shy of 400 HP. I'm sure I have a little more now, but I haven't had it on the dyno since I bought it.

The moral of the story? Get some kind of chip to increase your HP if you want more power. You'll also gain a little more mpg - at least I believe I did.

 

the only thing i have done is gauges! soon i will have a intake and a muffler/ cat delete, i dont really want to run a programmer just yet cause the truck only had 1120 miles! and i deff do not want to void my warrenty! DynoDynamicsNE there is no way i will ever be able to chirp the tires in third i have a auto where in your 6sp all you have to do is mash on it and dump the clutch!

 

Read my post again...

If I give her 1/2 to 3/4 throttle at around 10-15mph, she just rips down the road chirping the tires into 2nd and then they keep trying to break free up until around 40-50mph.

I'm not claiming anything other than what I stated.

Spinning tires and such = Bald tires, 6spd, or chips.

 

mines not going to spin tires at 1/2 throttle in 1st or wotever gear either...im just saying for the way it is now it has ample enough power to be lots of fun to drive and has the ability to easily accelerate or pass someone...thats all im looking for

 

My truck had less than 300 miles when I installed the Quad box, and it isn't a programmer. In fact, it's very easy to remove if I ever need to take it to the dealer for something. It works by intercepting the signal from the trucks ECM and modifying it to give you more power - it doesn't affect your ECM at all. There is a guy on here that works for Quadzilla, his screen name is Quad, and he'll be able to describe how it works better. I'd recommend the Quad if you are afraid of voiding your warranty (as I am).

And, I didn't realize you had the auto trans. Sorry about that.

 

Yes its true.Youll even see a fuel mileage increase. If your not pulling a trailer run it hard and it will make it break in faster. Run it hard and around 12k to 13k you will see a considerable mpg increase which should also give more power.

Also,for trucks with 48re trans,the tranny will teach itself how you normely like to drive. Meaning if you baby it trying to get better mileage,or dont tow a trailer thats how your trans will adjust itself to your style. My truck will spin the tires because I usually dont baby it. But at one plant that is 60 miles one way I drive for mpg, after a week of that I cant hardly get it break the tires loose

 

well thats good to know that eventually i will get to feel/see the cummins turbo diesel to its full potential cause as of right now i am looking for ways to get more out of her

 

Patience young grasshopper!!!! The Truck will open up a little for you when there is around 10k on her if you are towing..... If not you will slowly see a gain in mpg's after 15k.... Oh and drive it like you stole it to get the performance out of the 48re's learning program! I hated that about it! JB

 

I'm not sure about the statement that it doesn't affect your ECM at all. Read up for yourself in the performance & accy section and I think you will find that most consensus is the SMARTY is the only programmer that does not leave some sort of trace in one form or another in the ECM. If DC wants to they will find that you had a box.

That being said my friends all have the quad box and love it. But I won't be putting one on either as I don't want to risk the $1800 bucks I spent on the extended warranty.

 

My truck actually got around 18.5 on the interstate when I first bought it (first trip with 500 miles on the ticker). Now I'm getting 15 with 4400 miles. My truck was reflashed awhile ago, about the same time winter diesel took effect, so I don't know if the reflash or the winter diesel is causing the drop. I guess we'll find out soon.

 

The Quad isn't a programmer. It doesn't connect to your ECM, just the fuel rail and MAP sensors. The way I understand that it works is by increasing the fuel pressure, and using the MAP sensor, it does some boost fooling. I'm not an expert on it, but I don't see how DC will be able to tell that you had the Quad box installed if it's removed before taking it in to the dealer. I guess that they could possibly see the higher fuel pressure and boost if the ECM does some sort of data logging, but as for programming the ECM, it doesn't work that way.

Just my observations, the best person to get more info from is qzilla.
