The only reason I question the whole thing is due to the research I’ve done with just changing the exhaust. “There is normally no need to have a custom tune for mods like exhaust, TMIC or CAI's. The ECU will deal with these mods happily. This applies to mods installed before and after a flash tune. The ECU will relearn any parameters it needs to for proper operation. Experience shows that adding mods normally enhances the tune, as it does under a stock tune. A custom tune is advised for major work such as heads, cams and modifications that may radically alter sensor data fed to the ECU/PCM.”

That’s why I’m wondering if it’s worth it or at least something I can sit on for a while. I appreciate your thoughts and advice none the less!
