Tuner for 2015 GMC Sierra 6.2

Herd Thinners · September 15, 2015

So my new truck has a Sierra 6.2 has a corsa exhaust, k&n, and running 33 inch tires. I know my speedo will be off so I'm thinking tune and speedo adjustment.

1. Is the tune detectable if I resort back to the original before bringing it in.

2. Can I have multiple formats: performance, long distance, tow, original settings.

3. Is it safe.

4. Who has this truck tuned and let me know their opinions on what to get. Thanks in advance.

I've had all my trucks tuned except my current one (as of now). If your truck is tuned, the dealer can see it. If you detune it, the dealer shouldn't be able to see it. If you buy the autocal programmer, I believe you can have more than 1 tune you can upload to your truck but 1 at a time. Yes its safe if you go with a good tuner like Blackbear. He's the only one I'd trust but there are others. Is it worth it.. heck yeah it's worth it. The biggest difference is the removal or mostly removal of Torque management. That and the shifting. Between those two, you'll have a different driving truck, and one you'll enjoy driving.

Don't expect to get 50hp out of it, but it will be a noticeable difference.

If you convert to flex fuel ($300.00) and run E85 with the tune you can net 50 horsepower.

I tried a Bullydog tuner on my 08 Silverado 4x4 for a month. I could feel the diff. in shift points and HP. Now after a month I'm rethinking about getting another one. As far as mpg I did get about 14 mpg but I still feel its all in how you drive.
