I have a 2004 chevy silverado 5.3l, does this switch tunes on the fly? How much increase for mpg? what about HP?

It is not tune on the fly. You have to be stopped with your engine off and then turn your ignition on and off and different times through the programming process. MPH and HP vary. I've seen a little HP on my Ford but haven't noticed any real increase in MPG. Honestly; not sure if it's worth the money.

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

I'm pretty sure you have to install the Regular Gas tune to disable the speed limiter and V4 mode. That's what I got it for and it works great. Not a huge "shifting points" change. It makes the first 3 gears a little faster and more responsive but it's not a huge difference that will mess anything up.

yes it increase MPG and horse power on your car.. I have a very good experience with my Honda accord 99.

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. ;)

Well, I have the 6.2L engine in a half ton quad cab with 33" tires and it gave me a very noticeable amount of power. Approximately 25hp but with that and the change in shift intervals it hauls the mail and pulls like a son of a gun. Only thing I have to say is make sure that you place a jump pack on your battery or a battery charger while it uploads the tune. If the voltage drops too low at any time some files will be corrupted, causing nothing to work properly. This happened to me and I had to reflash the PCM at the dealership after towing it in cause the computer was all jacked up. As long as you give the battery extra juice you'll have no problem and customer service from edge is great.

Yes, works wonderfully. My truck had 156,000 before I purchased this programmer. After install I was getting an extra 4 miles to a gallon and could feel the upgraded power and response. Give it a try, you WON'T be disappointed.

Yes, you are good till going to another setting. Make sure you change back to factory before changing your battery(s) or getting a new inspection sticker. After either of them switch back again to MPG mode.

None, after running it for a while, what fealt like a gain was not, dyno showed same results a a drop in performance filter. Also mileage dropped, to 25 mpg from 29 mpg. I recently returned car back to stock, power is the same, fuel economy back up. Only positive thing about this unit is price, and sound. I had the Mopar unit, prior to this, and a K&N; as well, money wise, lesson learned just buy a K&N; replacement filter and save some time and money. On a side note if you are looking for bling and nice tone from engine, then the unit is worth it.

I used this in a stock 2006 f250 v10. It seemed as though I got some power increase, but I didn't notice any significant change in mpg.

No you can not . Tuners that do that are not good for the truck. This tuner is a great tuner to monitor ur truck and buy custom tunes from innovative diesel . They make great custom tunes for the truck , makes it run strong hard and safe . Tunes that switch on the fly only mess with how much fuel is being dumped in . That's a bad thing more fuel equals more heat . You have to balance air and Timing with it . This tuner u can switch tunes parked and take about 5 minutes .

I don't believe so. I have the 06 2500 duramax diesel w/ Allyson trans. It's pretty scary with it set to the 2nd setting and it even increased my MPG- how I don't know. I haven't and don't feel I need to go to the 3rd setting. Call Hypertech, that's what I did to confirm. Good CS and they'll lead you in the right direction. Hope this helped.

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.

Been awhile since I've used this tuner, but in settings you can change the tune to tow/haul mode. So return your truck to stock and then down load the new tune selecting the tow/haul

I was using 87 with the tune then went to 93 and It seemed to be better power and mpg with 87 but idk my mpg but I can tell I get better though

There are three power settings, 1. Tow 60 hp, 2. Race 80hp, 3, Extreme 100hp. I use # 2 Daily best overall shift and performance mix. Found # 3 gave best MPG when just highway driving. I have not had another programer but this made a huge improvement over stock.

When your driving you can have it on one of the four categories. I have mine on instant mpg, you can have in on Instant, average, rpm, or mph. You need to select manually. But once you do you don't need to switch it every time you turn your car on.
