One day ( not today ) I may look into tuning my M2c , but I am curious about people thoughts on below

If using a tune like Race chip or BM3 ( I know they work different but they = more HP ) has anyone measured that actual performance upgrades ? Not HP but 0-60, 1/4 mile etc .

What about gearing ? If you increase you HP by 50 or 100 - does that affect the transmission or diff ?

What about top speed ? do these chips increase top end ?

I saw a video where Race chip gives he m2c 500+ HP , but does that just make crazy burnouts or is the car really faster ?

real world result depends heavily on tires and driver skills

Bm3 removes top speed limiter, Racechip does not

Tune should get you anything between M2 Competition and M4 GTS numbers

Catless downpipes, good tires and a professional tune should in theory get you real close to M4 GTS specs
