EFILive FlashScan V2 with GM Diesel & Gas Tuning Option

It's a great product!

Excellent product for Duramax diesel, no other that works better... But, I HIGHLY recommend you purchase this tuner from an authorized dealer that will package a custom tune for your truck as well.

Awesome but really hard to use need to read alot and know what you are doing

Great system, unreal potential

it works good

Hardware works fine but the software is beyond terrible.....someone with the ability to write a usable user interface NEEDS to go work at the company. Go ahead.....try and buy a license, then spend hours trying to decipher what version you need, catching the right authentication code, then beat your head against the computer because your shopping cart remains empty. Do yourself a favor.....buy HP tuners and forget you ever knew efi live existed.
