Changing exhaust and intake
 

I'm about to change out my stock exhaust and intake.

My father is telling me that I can't just "change" them out, that it will require re-tuning because the better air flow will mess with the fuel injection.

Can someone please confirm that adding an aem intake and an aftermarket cat-back exhaust will not cause my car to need any type of ecu modding?

No, tuning is not required at all.

However, it IS recommended.

It is not necessary.

no its not necessary..

btw devlin, i like your new sig pic

Thanks, it was an old picture i found looking through my files :D:

The factory ECU is more than capable of handling the extra air flow.

Not necessary, our ECU naturally re-learns its fuel trims to always match stock programmed values. As in, it will tune for you - to an extent. You won't blow up or lose power or anything.

no offense but your father needs to "update" his "automobile" knowledge.

modern cars (in fact, since mid-late 1990s) came with ECUs with more processing power (higher bits) and be able to handle much more than just a few tables/workload. there is a preset value inside (enrichment table) which will adjust almost everything on the fly based on MAF (open looped) and Front O2 sensor (closed loop)

His father is old school...lol

I would disagree with this. Tuning is recommended in general because you can get something specific to your car (engine) and make some changes that can potentially make a difference in reliability. Basically, I wouldn't say that tuning is recommended because of the intake and exhaust, it's just generally recommended.
