Hi, I am interested in purchasing a tuning setup, and was wondering if EFILive is able to do CASE relearn process, before I decide what to buy. Specifically, I am looking to be sure it will work with a '07 Silverado NBS 5.3L. Has anyone had any problems or sucesses with this setup? I have read some other tuner outfits are having trouble with these engines and CASE relearn. Thanks.
