I've been using Spider Tuning products for awhile now and have Spider Tuning Boxes and Spider Performance Packs on my Giulietta and Fiesta.
There is a forum coupon code already ALFAOWNER
which gets you £75 off the more expensive performance packs however I've now got the code FOC30
which takes 30% off all of their products:
The £375 Performance Pack is now £262.50 (£112.50 off)
The £259 Micro Box is now £181.30 (£77.70 off)
The £199 Spider Tuning boxes is now £139.30 (£59.70 off)
The £129 Launch Control Pack is now £90.30 (£38.70 off)
They've also said they will have a new and easier to use site comming 1st July along with a new product the Bluetooth Performance Pack
which works with their new Android App to monitor and adjusted settings through your phone. I don't now the price of this yet but it sounds great
Hopefully more people can now enjoy the Spider box increases like myself and other members are.
