I have the Morgan Aero Racing Stage 1 ( high flow air filter and high flow exhaust ) and Stage 2 cams with the Garage 56 unlocked ECU optimized for Stage 1 and Stage 2.

The engine is now capable of performing much better at lower RPM so you don’t have to downshift quite as much and seems to be much more free revving. I would say the engine runs more smoothly than without stages 1 and 2 but I have to say my engine seems to run much smoother when I first start driving when the engine is cooler than after driving for awhile when the engine is hot.

2015 M3W, Morgan Aero Racing Stage 1, Garage 56 Stage 2, sport black, saddle tan, jeweled SS dash.
