Hello All, I have a 2015 Tahoe, and already upgraded the cold air intake, and added a Borla exhaust, and love the difference it makes. Now I am looking at performance tuning, and/or a throttle body spacer. I see a lot of people went to Black Bear. I live in Phoenix Arizona, so that is not an option for me. I also see the Diablo I3 being used. Can a novice car person use the Diablo.? or is going to a shop a better option if so, can somebody recommend something in Phoenix? Last question the throttle body spacer do they also help
