Question Air/Fuel/back pressure issue ... ?

I just installed V&H Power Duals with V&H Hi Out-put slip on's and seam to have developed a condition I didn't have with my prior setup (stock head pipe, Screamin Eagle Nightstick with a Stage 1 Breather kit).

The bike seams to be struggling with it's air/fuel mixture which gives the bike a "slight" stutter at and below 2,300 RMP's and every once in a while I'll get a huge hick up/lunge. I was assured by my dealership I was good to go since I already had a HD Race Tuner with the stage 1 but I'm starting to think I may need a dyno tune or a Auto-tuner? Or maybe I don't have enough back pressure with this new exhaust setup ... there's NO baffles in those slip ons?

Anyone have any input?
