Did a search and didn't find an answer so I thought I'd ask. I have a set of Mopar long tube headers and wondered if I can install them with out the ECU being upgrading. I know the better the motor breaths the more power it will make so to speak. I'm a little worried about it not running correctly but I thought the OEM ecu would relearn and adjust but I'm reading conflicting info, I understand it will not make the power that the Stage 2 ECU will provide.
