JB4 to buy or not?
All,
I have a 2019 C43 sedan. I'm in eastern Canada and only have access to 91 octane, so I will likely be limited to map 1, possibly map 2, but questionable.
My question to any owners out there with a 2019 C43 is, if you could only run Map1, is the JB4 worth the cost for performance gains?
During email conversations with BMS, they mentioned that I would not likely need the BCM module given I would only be running 91 octane.
thanks in advance
