Will this tuner harm my engine? I have the 2008 4x4 GMC 6.0

I have mine on level 4, it throws a code for the throttle position sensor.... other than that I havent had a problem with it for 6mos.

When I put it in tow mode my gauges don't work and it throws a hot engine response. When I put it in economy mode gauges work and temp.is fine.

So far I have had mine for 5 months and it has been great. Makes my 4.8 run like a 5.3 or maybe a little more. I just used it to tow my 26' camp trailer with no issues. Haven't had any trouble.

I have the 08 6.0 liter vortec max as well. It won't harm your engine at all, just make sure if you're running the level 4 performance mode or any other mode that requires 91 octane or higher (premium gas) that you do so. Other wise your engine will knock. Do what the manufacturer of the Edge describes and there will be no issues.Sources: US Air Force mechanic

I cannot speak for your engine, however with my 5.3, even with the program now removed. I still have to run 93 octane to keep the truck from skipping. Didn't do that before the programmer. Get a custom tune. You'll Be much happier

Mines been completely perfect! I just run it stock and change my tire size and gear ratio and I get better mpg than any of the tunes, just don't try to put 1000 hp in the engine and you'll be fine.

It won't hurt anything at all, as long as its installed properly, just make sure to break it into your car slowly. As in, after install, the ECM needs to calibrate to it. I personally recommend to run the car as normal, just no hard throttle pulls for a week to let it sinc in. But please do grab the accessport so that you can actually get some decent gains from the intake system. Let alone you'll instill a longer, safer engine life. If you got any more questions, please don't be afraid to ask. I'm more than willing to help you out.

As far as I know all you need to do is make sure you either run the engine so the 20% is all used up from the lines and the tank or just drain it all. Also ensure you clean out your air filter and reoil it. Set the carb to factory (because the change in percentage will throw it off the tune) and return the engine. Other than that you should be good l.

Yes it should work without any problems. I have the previous dual tuner and it works just fine. Wayne

It's worked ok for me with my gmc 6.0. Especially with the transmission firmness and speedometer adjustment since I run larger tires

I installed an air filter from napa along with a 4" turbo back exhaust at the same time as the tuner. Got 2 to 3 mpgs more on the highest setting. I leave it there all the time except for when im towing heavy I put it on Tow mode. So to answer, yes, you change it when you want and leave it alone if your happy where it is. Good tuner to start with.

I use it on my 09 Charger R/T and with all the options i can run a 1/4 in 12.1 secs. you have to bring your vehicle to a dyno to get your hp/torque. Mpg is based on your driving habits so you still wouldnt get an accurate answer. But with my 5.7L V8, when i use the mpg booster i can get about 25-26mpg on highway, 16-17city. But thats with a CAI and exhaust. If you do plan on using this tuner for your vehicle, i would recommend you plan on putting a performance a CAI and exhaust on your vehicle To get the most out of the tuner for the cost. You will also get more power and mpg with a CAI and a performance exhaust.

I don't think so, unless you had a tune on the truck before it lost the tpm, if you did and you returned it to stock tune then it should reset it.

Yes it will i have a 2012 ram 1500 this tuner is for hemi engines 5.7 6.1 and 6.4. Only draw back is if u tune the engine i have found u need to run a higher octane in your tank other that that its a great tuner.

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.

Need more info , the carb can be used on anything if the fit allows and the tuner knows what he is doing , since out of the box calibration is probably not correct

You will sacrafice fuel milage, mine went from 42 mpg to 38 mpg. But worth it to me. I've made mods to the engine and changed exhaust 2 or 3 times and the Auto-tune keeps it running at peak performance. No more costly dyno after mods!

I'm sure it does. I have a 6.0 and made my truck run much better especially in cold weather. Best thing to do is call Rotella hot line. Their pretty fast and will only take 5 min of your time. I run this year round and live in PHX AZ witch is the hottest climate in the country 120°F . So heat can't hurt this stuff either.

I think that since it operates on 10m and 12m, without a tuner, it should "tune up" with a tuner...........may ask the dealer for sure

Unicorn... When i bought mine i noticed a tiny bit of power increase only on the lvl 4 tune. I think they rate it at 25 hp gain, and 24 ft lb torque. The thing i really liked about it was it had firm shifts all the way through 3rd gear. Definitly going to help if your towing. But if your looking for just hp increase overall i would get a blackbear tune. Wont get number like a diesel but it will definitely help.

Doubt this would cause damage to your sensors. Ive used it back to back with no problems on a 2008 4 cylinder. Probably just have bad sensors.

B-4 you use I would check with your local dealership and ask ---- I didn't ask my dealership and it destroyed my engine to the tune of between $24,000.00 to $47,000.00 my car was a Jaguar XJ
