Hello

I have a 55 AX on a 3D Profile. I am running wildcat 15% Nitro with 18% castor syn blend. The engine has about 1 hour of runtime, starts wonderfully, never run lean, idles great and makes GOBS of power with an APC 12.25 -3.75. I am also running a MACS pipe.

The problem that I am having is that the midrange is nonexistant. I have a good transition to full throttle, but there is a deadband which is I guess is the best way to describe it.

Any suggestions ??
