Maybe this is a dumb question or someone already ask it, so don´t be mean haha... in the near future I'll putting aftermarket headers and a cold air intake for my mazda 3 hatch 2.5 (already have the catback w/o resonator installed) and i wonder if i have to do the ECU reflash as well, like obligatory, since the engine with that mods and with oem mapping will get damaged. I ask this because in my bike (800 cc) I have to reflash my ecu after putting a full exhaust system, aftermarket air filter and drill some holse on the airbox (oem was very tiny). Thanks in advance.

No you don't absolutely need a tune. It's better with one but not necessary. There's a wider range of compensation built into regular cars than bikes which are basically race motors tuned to the limit
