I was told that this would help the hesitation in my '00 400 exc. Has anybody tried this product. Is it any good? would you recomend it? The hesitation comes from a fast roll on the throttle.

I would not waste my time with the P38 ,does not make that much of a difference.Make sure your accell. pump is clean and that your idle is set at 1850 rpm.This will eliminate 99.9% of the hesitation.
