Hi JCIP,
My G/frnd and I will be spending five nites in Oahu, followed by four nites in Maui and another three nites in Kaui.
Here in Sydney we have a tuner called Peak Performance and they provide the Hartge kit for the MCS. I'm just getting to know the Mini2 community over here and they seem to be very knowledgeable about all the available tuners and suppliers of performance gear for the MCS here in Australia.
I think after my warranty period, I will have the Hartge kit installed along with matching exhaust system.
The JCWs kit will be arriving in Aus fairly soon but in limited numbers and along with a fairly rich price tag. The Hartge kit is currently sold here for $5000 (AUD)fitted with the JCW being $11000 (AUD)...ouch
Some of the guys with the Hartge kit say this thing is the bomb and it seriously Rocks!
Aloha
Eddie
