The most diffcult about mounting was to get the plastic enginecover of. (You need to open the oil refill cap first

)
After that, it takes about 30 seconds to install.
Power before 163 bhp, now 184.
Torque bfore 400 Nm, now 445.
0-60 mph before 13 seconds, now 11. (What on earth will I do whith all that extra time?)
The jeep feels like it´s 300 kg lighter. There are no better fuel economy, but the rear tire will wear out quicker.
What I think about the trim chip... Well, I would rather spend my money on something else.
