Just Bought 05 Denali

An in person tune will run a little cheaper or about the same price as a chip. If you go the Autocheck route, you'll pay more but its worth it. You can flash your stock tune in minutes if you need to go to the dealer for service.

Is a tune setup for better gas mileage going to be worth it? how would I go about getting it to the truck without buying software or something?

Any one of the companies in the link below have quality CAN tuners that offer decent power upgrades and options. However, for the absolute best resultss though, honestly, BB Custom tuning would be my choice.

Here is a pic of her. Now for the other questions. There is a switch that is mounted on the dash that I have NO IDEA what it does. Who wants to guess? Here is the pic of it.

Nice truck, looks just like my 04 Denali....

That button disables stability control.

 

[sdkilla99]

I know the button disables stability control , I'm talking about the switch above it.

 

[Freedom Motorsports]

Sorry, I believe that one is aftermarket, you may want to attempt to trace it to find out what it is for...

 

[ATL]

my denali doesnt have that switch, so i say aftermarket too

 

[Freedom Motorsports]

Yeah, ours doesn't have it either...

 

[sdkilla99]

Where should I start in tracing that switch? Should I take it to a dealer or a stereo place?
