Just wanted to say a few things of my experience with Blackbear tuning. I drove 1 hour 45 minutes to Schaumburg and met Justin and Jared. Both are stand up guys-polite and fun to talk to. Jared kept me entertained while Justin was doing his thing. Justin was very informative and answered all my questions to the best of his knowledge. We took a test drive and had to stop to make a few adjustments but he got the most out of my truck. My Denali has better acceleration,firmer shifts, and improved fuel mileage. I was getting a little over 14 MPG's via the D.I.C on my way down. I checked again right before I pulled into my subdivision and was at 18.8 I have nothing but positive things to say and feel very fortunate that I was able to get an 'In-person' tune. Thanks fellas
