Is there any tune specifically for Magnaflow mufflers? Thanks!

Is it possible to disable DRL (daytime running lights) on a 2014 Silverado using an ECM tune with the I-1000?

It's a great feature that gets rid of the extremely lazy throttle response down low on those trucks. To try it out, go into the User Adjustable settings, just ...

Hi Zach,

I haven't done anything other than load the default "Diablo Tune", I did add the additional setting to disable DOD, but that's all. Sorry, I am very new to this. Should I have done some additional stuff?

Hey guys!

Just picked up the I-1000 today. I ran through the basic steps as outlined in the user guide and everything seems to have worked fine with saving my factory tune and loading the new tune. My main reason for picking up the I-1000 was to turn off the DOD/AFM. That worked great, no more ...
