Hi all, so I have a 2004 Acura tsx with an injen CAI. I also have weapon r headers and a skunk2 catback exhaust sitting in my garage waiting to be installed on a warmer day From what I've gathered on other threads, the car will run a little lean without a tune. So I was looking into getting a hondata flash pro but aside from UR pulleys I don't really plan on doing any other mods except for suspension and cosmetics. So other threads are saying that a reflash would be enough. Would this fix the AF ratio without getting a pro tune or would I still have to take it to get it tuned at a shop?
