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
