i been having this problem where my car runs like ass when cold. i,m throwing tab code and all kind of emission codes and smells like its burning rich. now i could have a custom tune and the shop said the could turn all my emmission off with a tune and a custom chip for 550 and dyno pull. u think this will help. im sure as hell not putting my emission back together. i can still drive it but it takes 10 min to warm up then its fine. will a tune be worth the money.
