Rate of flow is not an issue at low RPM where turbo lag occurs in our cars.

I feel that the 1M is pretty linear compared to the 335 that I had but not as linear as the M3. With a tune it's gotten even more smoother and more linear than stock which is great and feels awesome. Now it's traction that I need to solve as you mentioned.

The 1M doesn't need more power low down, as I am struggling to control traction in 1st and 2nd gear anyway. It is the higher rev range that needs more boost, where the small turbo restriction comes into play.
