This group has been formed to support parametric tuning of GM vehicles using EFILive software, with emphasis on Duramax diesel truck tuning. Special interest in factors affecting cooling system performance is also promoted. Formed for the purpose of learning tuning, tuning principles and techniques, there will be occasion to download a .tun file now and then, but this is not the exclusive purpose of the group. It is important to develop a base of knowledge on what constitutes effective and safe tuning, and this is the larger purpose.

LOOK TO THE LEFT SIDE MENU OPTIONS, begin with "FILES", you will find tutorials, articles, tuning papers, and operational support of the hardware and software, but you must be an EFI owner and group member to enjoy these features. If you don't own the hardware, let me know, I provide an authorized discount.

To obtain EFILive, you can contact Enervative Product at killerbee@killerbeeperformance.com . You can also visit the site, www.killerbeeperformance.com for a variety of other services, including custom tuning service where you don't have to mess with any of this. It is all done for you.

Enjoy and "go smokeless"!
