BB tune on 4.8
I have recently purchased a used Tahoe that I am looking to get a BlackBear tune on and was just wondering if anyone has had this done on a 4.8 Tahoe and what kind of gains did you get from BB tune? MPG? Performance? I have already added a Volany CAI to it. Just want to see if BB Tune is worth...- KnuckleHead
