GDE,

Just a few more questions before I purchase the tune for my Canyon. I figured it would be easier to ask here than on the other site. I would like to say first, that I am glad this has finally been released.

If the questions seem dumb, please note that this is my first diesel and my first time tuning...

1. if I were to change tire size, I assume I can contact GDE to re-calibrate the tune for a fee, what would that fee be?
2. when prepping for my state inspection, GDE mentioned that I would need to switch back to the stock tune for about 1 month, I assume that this is something that is done with the existing tools that come with the initial purchase and without the need to call GDE. is this still the case?
3. DEF would still be needed (at a slower rate than OEM). Do I need to worry about the DEF shelf life/effectiveness.

Are there any other tips to ensure the tune goes well other than following the instructions provided?

Thanks again!

1. On the website it is $25 for the tire size change.
2. Maybe a couple days back in stock for would be enough. It takes about 5 minutes to flash back to stock with the Autocal flash tool sold with the tune package.
3. If should be fine.

The instructions are critical to the install.

good info in case anyone was on the fence, this was quoted from GDE on another site.

[quote]This will ease your concerns:

1. EGR valve is an h-bridge design and has amazing opening/closing force, build up is not a problem. Additionally, every time you turn the truck off, GM has an egr cleaning routing that runs. It cycles the valve full open and closed to keep the shaft/bore clean.

2. The DEF still runs the pressure build up and purge every drive cycle, so it is still keeping active.


Exercising the hardware is like exercising in the gym. Helps the hardware maintain functionality as it ages.[/quote]

Got tune loaded, the whole process took about 15 maybe 25 minutes most of the time was me reading the instructions a few times to ensure I didn't brick my truck. Then I had wait until the end of my commute to really open her up. My calibrated "butt-dyno" tells me things are good, she feels like a new truck. She pushes me back in the seat when roll on her at speed without the "1-mississippi, 2-mississippi" delay. I don't feel like I need to over anticipate a lane change from a stop when I'm in bumper-to-bumper. I'll check on MPG when the novelty wears off, I've been quite liberal with the skinny pedal yesterday and today.

GDE was great about answering questions I had and they were very responsive.

If anyone is on the fence, do it

Thanks GDE!
