C63s downpipe and tune
I bought my C63s and the car already had down pipe and tune on it. (358 Kw at the wheels)
The dealer told me in the future if the car experiences any trouble, it will not be covered by warranty.
My questions is; are those down pipes and tune actually detrimental to the car or can the engine/gear box support the extra power gains?
I don't really drive the car hard anyway!
Thoughts?
I was talking a tuning shop and the guy there told me this engine can support the extra power as the other AMP GT model has the same engine with more power!
I'm having to pay for a tune again because when I brought the car in the dealership, they cleared my tune as there was a recall update to be done on the car for the rear axle. And obviously they are not taking any responsibility for it now!
