The reason you see improved mpg is because you have more torque and don't have to push the car so hard during normal driving, then when you are cruising it holds back the fuel slightly, so you see a slight increase.
Use the power though and it will use even more.
My 120d (163bhp) was and auto and I saw very good gains in consumption.
177bhp 320d auto didn't see any gains in consumption, but good power gains.

I have a 320d (163bhp)and would question if the consumption is increased with the spider unless you take a steady pace of 50-60mpg
.....however there is definite noticable power increase with the spider over standard and this may account for the apparent questionable mpg gains that I have experienced.
I recently removed the spider for a BMW service and the difference is quite apparent along with the power, the spider seems to smooth the engine with less 4cyl deisel clatter.
Has the spider purchase been money well spent????I would say yes....
