Was looking to get a tune for my c350 (OE Tuning most likely) and was wondering if anyone has had long term experience with one? Any problems caused by the tune itself or wanting to go back to stock ?

 

I have a Eurocharged tune. Tune was done at around 96,000kms 2 years ago. I’m coming up on 129,000kms and the car is just fine. I changed spark plugs earlier this year as just regular maintenance and there was no signs of fouling or carbon on the old plugs. Any proper tune will be just fine for the motor, transmission and driveline.
