Yep, if play you will pay. To me 140 Kw's out of 2.5L diesel = A fairly high stressed engine for starters. We all would love more power. If you have more power over stock, chances are you're going to take advantage of it. I would With anything mechanical you only have one guaranty- at some point in time it's going to break down. Your just bring that day forward.Longevity of the engine is another consideration. If you ask more of it, it will spend more of its life to deliver that power.
