losing power at highway speeds

I have a 2008 roadstar with 3" Hardchrome long shots. I have a Hyper charger and a power commander 3. Ever since i have put these pipes on, at highway speeds it acts like a V-8 running on 6 cylinders. It bogs down and spits and sputters. I have to roll into the throttle to overcome it. Every time i hit an incline it does this. I have had the bike remapped but it hasn't fixed it. Any ideas. Thanks
