I know I am probably asking questions asked before so sorry in advance to all, but... is a pro tune same as a customs tune? or am I confusing the two?
Oh, no, good question... A Pro Tune is just one from someone certified as a Cobb Pro Tuner by Cobb, so it could be flash or custom, it's just guaranteed to meet Cobb's safety parameters and not bypass anything. Cobb has their own "Off The Shelf" stage tunes for free but aren't very optimized and have far too of an aggressive list of requirements that aren't necessary. You can run their free Stage 2 stock, but should have an IC upgrade for Stage 3 that's it.. On the other hand, a 3rd party Pro Tune Stage 1 without even an intercooler typically outperforms the Cobb Stage 3 and is safe to run stock. These typically are from Stratified or Dizzy and only run $75 and are well worth it over the free OTS tunes.
