I have a 2001 silverado 2500 hd 6.0 . Will it improve gas mileage.

I put this tuner on a 2007.5 Silverado with the 5.3. Already had a K&N; cold air on it. Put a lift on truck with bigger tires and was getting 11-12 mpg. After the install of Bully dog, I am getting 14-15 mpg. Really just wanted tuner to help adjust trans after bigger tire install but gas mileage is a definite win. Also reads codes on engine.

It can do either depending on how it's set up. Lots of different settings for power or fuel economy

If you can get it to work! I have had mine for over a year and it still does not work. Calls to the tech support line went unanswered. I did get ONE repsonse from me emails; they told me to ignore the install instructions and "just plug it in".......considering this has fried other peoples ECU I have just given up; better to have my truck running than burn a $1,000 ECU. Good luck if you buy this.

It improved gas milage on my 09 JKU. But inly if i used the highest setting and I had to run premium fuel then.

Gas mileage seemed to get better when on the highway. Took a trip a couple weeks after installation and got around 18.5 generally. The increase in torque was noticeable. Fuel mileage around town has stayed at 13 this winter however(cold climate).

Zach Yes I have a08 Dodge 2500 with the 6.7 cummins, I use the 15/40 oil in the engine, and the 75/90 in the rear end, and the Max ATF in both the transmission and the power steering. all are working great , I gained 2 miles per gallon and the trans shifts smoother as well Hope this helps Greg

There is definitely a noticeable increase in power off the throttle but I really didn't note any significant improvement in gas mileage, but I added a lot of extras to my truck at the same time that increased the weight such as a sports guard and winch and larger tires. I would look at adding the Fitch Fuel Catalyst for better gas mileage. It is a couple of hundred bucks, but worth every penny.

I installed this in my 1999 2wd 4door and you definitely feel a difference. It's best paired with an aftermarket exhaust system. Together, you get better throttle response, torque and a small increase in fuel economy. Unfortunately I can't provide numbers other than about 2 mpg better than when my truck was stock. Blazerforum.com has a lot of members that can help give you more accurate numbers if you need. Good luck!

I did a few things all at once, adding the Airaid was one of them along with cat. back exhaust system. I do get a little better gas mileage, I have less low in torque but more top end. I am happy with it overall, it did change the sound of the car a little. I don't know if this helped at all

Yes. Thats what i drive. I did the fuel saver tune and get roughly another 2 mpg. But I also have an intake, throttle body spacer, and an exhaust. So instead of the stock 18 mpg highway im at 23 mpg.

Sorry, can't answer this question since I've got no experience with a 2001 GMC Sierra 2500 HD SLE truck.

It worked on my 2011 JK. The manufacturer's specs should indicate which years are covered. BTW, it doesn't really increase your gas mileage, it just adjust your odometer/speedometer to accurately reflect your mileage/speed. When you go to a larger diameter tire, the number of wheel revolutions per mile decrease, which makes it seem like you aren't going as far or fast as you really are. This accounts for the apparent decrease in gas mileage, and can get you a speeding ticket if you aren't careful.

It will give a gain in power to help with towing you may see an increase in mpg as long as driving style stays the same it dose have a programs from towing on it or like me a cold air intake and from what I can tell is it has helped with going up will not shifting as much and still getting 19 unloaded and about 15 with the bed full of wood

Lisa I bought the tuner to go on a 2006 Chevy 3500 Express van. I pull a 30ft car trailer with it. I have had it for a month or two. I have seen a gas mileage improvement of 2 to 3 miles/gal. Which I drive long distances. It does improve the power and fuel economy. If you drive a lot a mile or two per gal is a great help.

Better throttle response. Gas mileage goes down about three per gallon. You need to add the throttle spacer and possibly stainless steel dual exhaust for best performance.

Yes, primarily in lower gears. It dose not, however, improve gas mileage--despite the claims.

I have an automatic and by using the 87 Octane tune I improved my mileage by about 4 or 5 mile per gallon. Plus it performs much better as far acceleration/much peppier. Also went to a larger tires and wheels re-calibrated for the new height and it corrected the speedometer. So everything I did was an improvement over stock, so I would say it would help with a standard also, but not totally sure.

The 40410 and the 40417 will both work on your truck as long as you have a gas engine just note if you plan to run the performance tune you will need to run premium has 93 octane or higher any other tunes should be fine with regular i have my chevy set to the tow mode with higher shoft points and firmness and usualy run mid grade gas unless the wife gets gas then she gets the cheap stuff took a 600 mile round trip just the other day and averaged around 19-20 mpg with 35 in tires

yeah i noticed driving over 67 mph my gas mileage got better. increasing rpm's gives it a nice acceleration which allows smoother shifting.

yes.. it made a 2.5 mile per gallon difference when pulling (5000 lb trailer) saw some increace when not pulling 0.5-1.0 mpg. I also used a high flow air filter with it.. no downloads
