Power and overall feel coming from the engine is important to me and hearing that they like it aside from the fact its lacking power, being a detuned unit should make tuning it an interesting experience. A few hundred dollars later after purchasing a tune we could be well on our way to experiencing the kind of power that wakes up the XE-S enough. Now I just wonder what the tuning potential is like in these, who knows what sort of power is waiting to be unleashed.
