I have an aem intake, catback exhaust, and a midpipe. I plan on buying the access port for a custom tune by mazda maniac, but is the car ok to drive before the tune is uploaded, i understand it can take a few weeks for the tune to be done and dont really want to have my car lying up that long waitin to drive it as i love to drive my car and have a short summer.
Thanks.

a tune is not needed

This would be well within the realm of the fuel trims...no worries.

The catless midpipe will give you the ability to tune it leaner though with an AP to get better performance without having to worry about the CAT frying

A tune will consolidate your gains but driving without one with those mods will not harm your engine. Get it tuned and don't worry about waiting
