Full exhaust without a tune

SouthArk370Z

The rule-of-thumb seems to be that if you make just intake mods or just exhaust mods, you shouldn't need a tune - the ECM will adjust. If you change both the intake and exhaust, you need a tune. YMMV

Resetting the ECM is simply removing one of the battery cables and waiting a few minutes for the capacitors in the ECM to discharge (or press the brake pedal to turn on brake lights and drain the caps). You may need to perform the window reset procedure after restoring battery power.

Yes, stock intake right now with OEM filters. Thanks SouthArk370z. Will do that.

If you change the intake and exhaust at the same time you need a tune?

It depends. The ECM can adjust for a certain amount of change. Once you exceed that limit, you need to retune the ECM.

In many cases, changing just the intake or just the exhaust is within what the ECM can handle. But it may not do it as well as a retune.

To get the most from any mods, a retune is a good idea. Or if you just want a little more oomph/responsiveness in your OEM setup.
