2012 GMC Canyon

[Nick The Great]

Nice truck!

 

[RebelThunder]

Sweet. I like how the winch is pretty hidden.

 

[MOPWR2U]

Stage II ?

 

[buRRp]

Oh yeah. But I don't think it will do well as a dd.

 

[buckshot85]

Looks great. What type of mpg do you get with the 5.3 in that?

 

[MOPWR2U]

I've never checked. I have no idea what gas mileage it gets.

 

[drperry]

Nice rig!

4.10s and the 5.3? That fWONker must scoot!

Get that biatch BlackBear tuned ASAP!

They derate the 5.3 a tad in the GMT355s

I've got a question about "tuning" the truck. I read lots of threads about how someones truck is all that, because it is "tuned", but what does tuning really do? Doesn't it advance timing, and alter shift points in the transmission for better performance?

I use this truck as a multiple use vehicle, so it certainly wont be becoming the "stage II" vehicle that I posted above. I was just joking when I posted that.

One of the uses of this truck is to tow our 18' auto transport trailer at least every other weekend. The trailer can be loaded with ATVs, side by sides, or even my fairly light weight '85 CJ-7. When I've got the CJ on the trailer, I'm at the rated maximum towing capacity for the truck. I tow in the southwest desert, where temps can get quite high. I remember coming through Baker, CA, and as I started the climb up the Baker grade, looking at the roadside thermometer they have in Baker, and seeing 122 degrees on the thermometer. Wouldn't advancing the engine timing be the absolutely last thing I would want to do when towing in high heat?

Another use for this truck is backcountry exploring, which often times gets me in the middle of nowhere, and refueling can be a challenge. I have had to by cheap Pemex (Mexican gas) a number of times to get back home. Mexican gas can be pretty poor quality gas. Not sure I want to be advancing the timing if I'm going to have to run crappy gas in the engine at times.

Another question --- where do you get a "blackbear tune" done? No place in this area does ECM tuning, and I'm thinking the closest place would be Las Vegas, which is 180 miles away. How much gain is there with a "tune", and is it worth taking time off work to drive 360 miles round trip to have it done? And should it even be done at all, with the towing, heat, and poor gasoline concerns I have? I'm thinking, leave the engine alone.

You should start a thread in the Blackbear section. You will get tons of replies.

The overall driveability is so improved, you will wonder how you ever drove without the tune.

You needn't worry about engine damage from timing tables. I too worried about these things years ago before getting my first tune. Now, it is the first thing I do after purchasing a new truck.

Start a thread over there, and get some input from Jenna.

Some people get better gas mileage, others get better power, some get both...

Myself, I just got the power bump without the loss of fuel mileage.

What the custom tune does is tune your ECM for your engine. GM uses a canned tune that will run any 5.3, it is not optimized for your specific engine and its manufacturing differences, mods, location and all that fun stuff.

If you go the auto-cal route, you can revert to factory programming in the event of bad gas, or even get your tune based on the bad gas

It's not just timing that gets changed, your fuel tables are also adjusted.

The BB section should be able to get you more detailed info
