On offer here is a Steinbauer tuning box to fit Vectra C 2.0 & 2.2 DTI's. I removed this from my Saab 9-5 yesterday (same 2.2 diesel engine as the Vectra) and it's in perfect working order.
The performance difference with the box fitted is unbelieveable. In my car it certainly felt far quicker than my old Vectra 1.9 CDTI (150).
Unlike a lot of tuning boxes, the Steinbauer one is TUV certified, which is a testament to the quality of it. There are 4 performance settings, which you can set depending on how much extra power you want - full instructions are provided.
I must stress that this box is not exactly plug & play - yes, there are only 3 wires to connect, but one of them needs connecting to a wire on the injector pump. It's all on the instructions, and having done this install I'm more than happy to help out if I can.
On the plus side, as there's only one wire to connect to the injector pump, the box itself can stay hidden wherever you want - I had it under the dash on my Saab, with a single wire going through the bulkhead to the injector pump.
I'm looking for £150 for this, including postage to the UK or Ireland; no offers please! The new price of this boxes is a lot more than this! Paypal preferred.
PM me if you're interested. Thanks for looking
