Clean you MAP sensor, I have heard of this happening before when someone was getting loud popping noises attempting to floor it. The MAP sensor is under the air box mounted on top of the intake manifold, remove the MAF sensor (two torx screws) from the air box/charge pipe to turbo, remove the air box (one torx screw) and grab yourself a screw driver.

Wide open throttle at 2500 rpm is putting a high load on the engine especially in the higher gears.
The problem could be a variety of things such as a loose boost tube, loose vacuum connection, carbon build up on the valves or a failing high pressure fuel pump. This is just to name a few.
Most importantly, is the car giving an error code (CEL) or a high engine power light (limp mode)?

Check the hoses from the turbo down to the inter-cooler on the passenger side. Had the same problem a few weeks ago and found the hose that mounts on the inter-cooler had come loose. There is a triangular splash shield held on by 3 Phillips twist screws blocking the view of this hose where it mounts on the inter-cooler.

Link for removing the upper half of the airbox, there is one more torx screw between the PCV hose and the bottom of airbox on the passenger side.

I'm sorry I don't know anything about your Mini and can't pretend to, so very different than the ones here in the states. You can't even be sure that your engine is tuned for our gas since it's so very different. I don't even know if anything is missing since you don't have a MAF sensor, haven't seen many threads on your engine.
