Matt,
you should have been sorted by our MSN convo

Everyone else,
You only need live mapping if you want 400s or larger. Greens can be done either OTS or DIY.

Approximate price guide as follows:
£150 for stage 2 chip if you already have stage 2 or £565 for stage 2 kit fully fitted

£100 extra for hard/software to make the above closed loop capable.

Lambda boss fitting: (Including SS boss) £40

Bosch Lambda sensor £80

Wiring up lambda heaters and signal wiring to ECU plug £50

Providing you dont need any parts or anything, then that should cover it. DIY kits will also be available very soon for stage 2 conversions.

**our stage 2 is 803s, 3bar etc. Often known as a 330kit.
