I apologize in advance for my ignorance. My knowledge on cars is limited and I’m very new to mods. I just got a 2015 Honda Civic coupe (ex?) a few months ago. Everything I read said cold air intake is the best place to start. Great. I got a k&n for my 18th birthday. My dad said I need to get my car tuned to it. I call the auto shop and they said no, it doesn’t need that, they can just put it in and it’ll run fine. Then I’m at a car show and someone tells me that the auto shop was full of bull and it could really harm my engine having it in there without a tune, so I should get flashpro. So I’m really lost. Advice is greatly appreciated.
