Can anyone shed any light on the below....please!

As I hit 7500rpm and stop accelerating or back off the throttle a little the power completely dies, then if you slowly come off the throttle more the power suddenly hits in and lurches you forward for a second. It only seems to happen at 7500rpm and can be very scary when in a corner. Backing off the power a little to then have a surge throwing you forward and off the racing line and nearly off the track!
I have had a diagnostic check and spoken to a coupel of dealers but do not know the cause of the problem, any help greatly appreciated.

Also does anyone know of a garage when I can have a dyno check which may flag the problem in or around London (SW11)
