Alright guys i did a search and (didnt go crazy) but i didnt find a thread dedicated to different tuning programs.
Im curious what you guys have used and what your results were.
what are the pros and cons? long term?
Im just doing some research because i havent fooled around with them yet and may want to in the near future.
I have a 2010 silverado with a 5.3 and 6 sp auto
