Check for ECU Tune
I recently purchased a 2011 E93 from a private party who was the second owner. I asked him some questions that he didn't know the answers to which after taking a much closer look than a PPI, found the car had been modded in the past (aftermarket shocks, OEM muffler mod, aftermarket diffuser and front Splitter removed). So now, I also wonder if there is a custom tune running but I don't know if there is a way to check.
I tried searching the forums but didn't find anything. Thank you for the insights!
