I finished my flap delete and decoke last week and have driven the car about 500 miles since then with out problems.
Its made a huge difference to the exhaust noise and I now no longer have suicidal rattle noises coming from the inlet manifold when the car is stationary and blipped to 2000+rpm.
Torque is a little down which is noticeable in 1st and 2nd but a remap should sort that.
None of the flaps where actually broken in my car but the whole assembly was extremely loose hence the rattle. I removed everything including the input linkage and filled the whole with an m14 bolt, nut and lots of sealant.
I also gave the upper manifold assembly a lick of high temperature paint
