Hello !
Writing from France and happy to find someone interested in these tuning boxes.
I will be more confortable with money begining of 2009 and I was thinking of bying one of these : my choice SPIDER ou VENOM. In France it is about the double in price. So I was thinking to "import" from England.
Anyway, I will follow this post very carefully.
And I do this for the same reason : wonderfull car but horrible motor/gear box.
I also have a SEAT TOLEDO new model with the 2 liters 140CV from VW. Nothing compare !
So good luck L-Finesse with your installation.
Bye
PS : hope my english is understandable
