Default EFILive Supported tune file needed for '07 Classic 2500HD 6.0 4x4
Does anyone have a stock or performance tune file for an '07 Classic 2500HD 4x4 LQ4/4L80e?

The tune I pulled out of this truck is not supported by EFILive...

Original OS: 12597120

EFILive Supported OS = 12613248 or 12619624

I found a heavily modified H2 tune with 12613248, but was hesitant to start with that one.

I have 12613248 but it is in Tunercat format. I could load it in a PCM and read it back out as a .bin if EFI Live will open that.

Is that an early version of the OS from your truck?

Send me your vin and will get you the updated OS for it tonight.
