I have a 99 Silverado 2500 6.0L that gets 12 mpg. A friend recommended this to me. What kind of mileage can I expect to get with this? Thanks!

It depends on the setting that you put on but could be more or less or the same not sure exact numbers

I have a 99 Silverado 1500 5.3L and i was getting 18 MPG. However i put a 6" lift with 35" tires on it. My MPG dropped down around 13. After i put the programmer on i usually get 15 MPG driving conservatively. However, after i perform a oil and oil filter change, and clean my K&N; air filter i will get a high 17 MPG for several fill ups then it starts dropping to 15.

I did notice a difference, especially pulling the 5th wheel camper. I went from about 8 mpg to 15 mpg with my 6.0 HD

That's pretty damn good for a 6.0! I get 13 to 14 with my 5.3 tahoe. That's up from 12 ish before the bully dog

Maybe a minor MPG increase but not enought to brag about. I think it depends on your cruising speeds. Most roads I travel are 60-70mph and get between 16-17.5 MPG. I receive 18-19MPG when traveling 45-55. I noticed a slightly improved response after installation but don't expect a race truck. The sound slightly improved...mostly from Borla Exhaust.

I don't see it causing harm but being such high miles you may not see the affects as well. I would probably buy it juat ro try to get the last bit of juice out of the motor. I'm not a mechanic just a truck enthusiast.

I also have a Dodge with the 5.9 Cummins, stage 2 cold air intake with a straight pipe. We must have identical trucks, but mines an 05. All I can say it that I ran the smart on performance which adds 100hp to your 325 making it 425hp, and boy does it make a difference :) (ran it on performance for about a year) . With that being said I just changed my trans last week, lol. Got a complete rebuild all heavy duty parts for 2500$, with the dodge tranny you will probably be doing the same thing. Also, I'm 33 so I didn't do a whole lot of "beating" on the truck. Just your average race hear and there. ;) I also have a Dodge with the 5.9 Cummins, stage 2 cold air intake with a straight pipe.

Well I have a 2006 f150 fx4 and I was getting an average of 10-12 mpg in the city and 14-15 mpg on the hwy. I have nitto 305/55 r20 tires and if I run it on power mode with premium fuel I average 14 mpg no matter where I go towing or the truck alone and now I run it on economy with reg fuel and average 15 mpg unless I'm pulling then I only get 13 mpg. Hope this helps!

You may get 1 or 2 mpg better but its not a guarantee. Mostly depends on how you drive, how long and often you idle the truck and also fuel quality.

I didnt notice any change on MPG. I have a dodge ram 1500 5.7 and always get 12.9 around town and and roughly 17 highway. My tires are now a year old and look as good as when i put them on.

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.

Dusty, I can't tell you how much of an improvement it was because I hadn't really kept track prior to the conversion. However, I did take a trip from Oregon to Yellowstone and then down to Colorado this summer in my fully loaded down 3/4 ton suburban with a 5.7L V8. I am not a slow driver either. I typically do 75 to 80mph on the freeways and backroads. Anyway, I averaged 14mpg which I was pretty happy with considering the weight of luggage and a larger family. Hope that helps!

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.

Before installing I was getting between 27 to 29 mpg highway. After installing during a 3000 mile trip I averaged between 31 to 33 mpg. I used a fram filter with it. It was installed on a 2005 Focus

I thought I might have seen a 1 mpg increase in the early months, but now I'm not sure if that was maybe due to something else. I haven't really seen anything that would indicate a significant decrease, either.Probably I'd say if there is a difference it's not much more than 1 mpg either way. I do mostly drive the truck around town, though and when I do take it on longer trips, I get away from using CA gas, which usually increases my mileage regardless of anything else due to lower ethanol content.

On the highway, with the gas saving tune I gained a couple mpg. It does really good with premium fuel. In the city it's not that great. If you drive a lot of highway/freeway miles then it's worth it. I put dual flowmaster super 40s and a K&N; on it as well and if I drive right I can get 18+ mpg on the highway

final gasoline grade depends on which tuning you choose.I chose the 87 octane tune and have not really noticed any gas mileage inprovement. I combined the tune with a air intake system and the truck has move punch but not better gas mileage.

Your lucky, I only get 11.2 mpg. I haven't tried the performance programming yet. I am only using the tire size setting for my FX4. Let me know what you get for mileage.

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
