I'm totally blown away. Perhaps I'm missing something. Can someone please quantify the actual difference in terms of HP/TQ between the two?

To me it almost felt as drastic of a difference going from stock to 91 Stage 1 as going from the 91 Stage 1 to the 93 octane version.

What a screamer. Holy hell.
How does it compared to the GT3 now?
The GT3 is just brutal. It sticks like gum to the road, I have no traction issues. Assuming equal traction, which may be difficult to achieve on the m2, the m2 will give the stock 991.2 GT3 a run for its money. The tuned m2c's weak point in definitely traction. Engine is very strong.
