The same for me, it took a couple of days but then I received a PDF with pictures. But it sure would have been better if they would have marked the cables with the function/sensor. But yes, one connector to the MAP sensor (on top of the engine) and the other one to the Boost control valve (front bottom). Take the skid plate down (like 7 screws) and you'll get to the boost valve easier.
So I got the racechip installed on my
Cupra 265 and definitely see some performance improvements.
I still haven't made my mind up however. The power delivery in
lower gears is very linear and the rachechip does seem to just enhance the performance with extra power, but in the higher gears (particularly 5 & 6) the chip doesn't seem to know what to do in the
lower rev ranges. for instance:
If I'm at low speed/revs in 6 and just floor the accelerator, the power fluctuates up and down before settling at what seems like the power range at pre chip installation levels. Gives me the feeling that for some reason the chip works better in the higher rev ranges and in the
lower ranges doesn't enhance the performance but change the natural behaviour of the engine, which is not very nice.
I'll see how it goes , but I'm not sure if the performance gains in
lower gears are worth the tradeoff for what seems like a completely different engine behaviour in the higher gears..
