Hi, I currently have a 2015 ST3 with a muffler delete, resonator delete, and a turbosmart BOV. I'm looking to get a cobb accesport from Stratified with the snap crackle pop tune. There are 2 options on their site, an $500 one and a $700 one. Flash tune VS Custom tune. Ive never tuned my ST before and i dont want anything special, just the snaps and pops lol. Is there a certain one i need to go with?
