ECU tune BEFORE or AFTER mods?

A simple but stupid question. Is it recommended to get an ECUTek done before or after all the mods added, and if after, if you get the ECUTek done before, is it going to affect the mods that much when you add on? I have a 2019 Sport Z with long tube intakes, I'm looking to add high flow cats and exhaust at some point.

You need a tune AFTER the mods are installed so you can maximize the gains from those mods. The tune will adjust your fueling/timing/etc to make more power based on the mods you installed previously.

Do the tune after the mods. Otherwise you're wasting money.
