I recently purchased my SXT V6, I put on a cold air intake, went to a muffler shop who only really recommended to cut something on my exhaust to make it sound better, which, yes it does, but I have seen zero performance increase. In fact, my 0-60 if I go strictly buy the 0-60 on my gauge is actually slower. lol. My first day i bough the vehicle (2019 has 6k) miles. was 6.0 flat. no sport mode on, nothing. Now it is around (6.5-6.9) with the improvements. Is there anything I can do to help my 0-60 at all? I would love to just maybe help it by 1/2 a second, I know 1/2 a second is a lot, but getting it tuned seems to be the next recommended thing, but that seems to void my warranty. UGH. Any help?
