Flat spot in HP/Torque curve?

I've been driving around in my '06 JCW coupe for about a year now. I never really noticed it before until someone else with a JCW car drove mine and mentioned it to me that I have kind of a flat spot in the powerband from about 2200-3200 RPM. The car is full JCW with Mini Madness header/cat, Mini Madness intake, and stock tune (for now). Anyone else ever notice this before?

I just ordered the M7 16% pulley, colder plugs and wires, and am planning on having a custom software program written for the car. Think this might help?

No. Wait till he does a tune party out there or give him a call and ask about his remote tuning solution.

Jan's magic is a definite cure for the dreaded flat spot!
-You may have a bad plug or 2,dirty air filter.Attending to these after my tune cured a hesitation that I had at 2k.
