Hey, I'm new to the site and pretty new to the diesel performance world in general and while I have gained a lot of good info from reading this site and through many hours on other sites and I still have a few questions. The one thing I just can't find anywhere is what the big deal is with Idaho Rob tunes? I know EFI Live is the best option for tuning on an LBZ or any Duramax for that matter but I just want to know what makes his tunes so special. Any help would be appreciated. Thanks!
