Following, usually the zilla peaks around 3500-4000 rpm. Do you have an AFR chart?
No i don't have the chart I'll see if I can get one.. haven't picked the bike up yet.. was the (final) run.. trying to find out if I should take to another shop or not..
may or may not be tune related without an afr chart to reference it's hard to say. could be a clutch issue also. you might want to take it to a better equipped shop if they are trying to tune your bike without having an afr reference point.

Most of the time you see the dip down around 2200-2500 rpm. You don’t normally feel that accelerating. What is the CR? As was mentioned have you beefed the clutch up? If the clutch is ok and your AFR is good you might try a Fat Cat perforated baffle.

I was told the fat cat perforated was the boarzilla baffle .. please correct me if that's wrong?
