Hey all..I'm Shawn from BC, Canada. New to the whole tuning thing...don't know anything about it...looking forward to learning and sharing what I can. I just picked up my 2018 ZL1 from a performance shop where I had a stage 2 plus upgrade installed and 2 tunes written. I am now the proud owner of a HP Tuner and need to learn what the heck it does...lol
