YOur High compression motor is probably building boost at 2k
RPM. Mine does with roughly the same compression. Only about
3psi but still something.
Try this, I have a few friends with 4kq's, etc. 4 of them
running around. Drive in second at 2k RPM. Both punch it. The
NA motor will jump ahead untill a second or two later when you
build boost. Then you'll SCREAM past them.
At least this is my experience. With 8.8:1 and k26. But I
dont have the MC-2 electronics. YMMV
