Whats up cgm family. Looking to pick up a new hobby aside from my career. I would like to do my own tuning, and eventually stem out, and help others. Had my 6.2 Liter tuned by 3 different tuners, and honestly i just do not feel like ive gained anything. Is it just me, i literally run full bolt on set up. Would like to know if anyone on here does their own tuning, planning to buy all the software, and mess with some numbers, I dont mind my truck being the test dummie.
