Hi,
I went and installed the complete JCW Performance Kit, hardware wise. I went and bought all the hardware, brand new, for $450, which included the Airbox and the Exhaust, from someone who bought the complete kit, but only wanted the software portion of the Kit.
The original kit was for the N14 engine, while I have an N18 engine. The exhaust installed w/no issues, but the Airbox on the other hand, needed to be modified, due to the High Pressure Fuel Pump being in the way, as well as the Lower Airbox portion from an N14 engine needed to be installed in place of the N18 one, due to to the amount of fasteners.

To date, here are my Mods:
Replaced all the Chrome Pieces w/Black ones.
M7 Speed Turbo Heat Shield
WMW Resonator Delete Pipe
John Cooper Works Aluminum Strut Brace
John Cooper Works Performance Kit, including the Exhaust and Air Box, minus the software.

Left to do:
A larger Intercooler w/a JCW Turbo, and the JCW's Software Kit

As it stands, my MC can easily do well over 130+ mph, in 6th gear, w/o downshifting, w/no strain at all.

Now here's to my question, which I'm sure has been answered before, can the software portion of the JCW Performance Kit be purchased separately?

Thanks!

 

Possibly, but I think only a dealer would be able to answer that for you, and it would likely cost more than an aftermarket tune.
