Anyone else have trouble tuning a switchback?

I was wondering if anybody else had trouble tuning a switchback, and if so how is the easiest way to tune one.

What kind of problem are you having? A good reference is Easton's tuning guide : http://www.eastonarchery.com/downloads/

Yeah, a bit more information would be a big help for us in order to help you.

well i cant seem to get my WB and my cobra pendulum sight to cooperate.
i can shoot at 15 yards and be dead on but at 20-25 yards it shoots to the right 3 or 4 inches

I've never used a pendulum sight, but it is my understanding they can be a real booger to tune... That being said have you checked your center shot either via the walkback method or through paper tuning??
