I have recently added on my 2012 scion tc a cold air intake, tsudo catback, dezod green headers, and RS S-Pipe. I was wondering if it would be damaging to my car if I did not re-tune it for the new mods. If a re-tune is possible, will disconnecting my battery suffice ( as the ECU will reset itself)? Or would I need a professional tune?
have the same problem?
