Installed PCV from Fuel moto, lost all low range power

Hey guys.
This weekend I put my PCV on that i purchased from Fuel Moto with pre downloaded map.
I have the Nightstick Slip on muffler right now with plans to change to Rinehart 2-1 later this fall or winter.
I also installed an Arlen Ness Big Sucker Stage II AC.
First I installed the PCV, with just the slip on. I started the bike up for a bit and it seemed to run good at idle and the throttle seemed more responsive.
Then I installed the Ness AC.
I test rode the bike for about 70 miles yesterday, and it seems that i have lost my low range power.
I can now hear the AC sucking in air, and am concerned that maybe I am taking in too much air, or not enough fuel is being delivered.
The bike runs pretty hard after 3,000rpms, meaning, now i feel like I need to drive the bike at Higher rpms, but there is some lag or something until I hit higher rpms. I called Jamie at Fuel moto, and he said there should be any loss of power at lower rpms and they have tested this set up thousands of times.
He recommended just unplugging the PCV and ride the bike for awhile and see if i notice a difference. And then let him know and perhaps they can re download the map.
just wondering if you all noticed anything like this.
My pipes were turning golden with just the Nightstick slip on, but am thinking that they have really turned blue by the o2 bungs at the end of the head pipe since I installed the PCV and Air cleaner.
Any help or insight is appreciated!
thanks

By chance did you forget to unplug the O2 sensors?

I went the same route as you did.

PCV, Fuel Moto A/C, Rush 2 into 1 primary pipe, and the Nightstick.
The bike runs very nice. No issues.

Open the nightstick with the open end cap and run 8 disc. Doc

I am still running the stock head pipe, but i did unplug the 2- O2 sensors under the rt side panel.
I removed the PCV last night and left the Ness big Sucker AC on and couldnt tell the difference. Low end seemed the same.
So now Im thinking i am just crazy.
First I thought WOW, I got some good top end power now, which may have made me think that i lost low end power.
And with the PCV removed the low end power was the same, and couldnt tell the difference in top end compared with the PCV.

So that would mean removing 2 discs and add the open end right?(there are 10 discs in there i think)

I called Fuel Moto and they said it may be running a little too lean still, so they are going to send me a cooler map that enriches the fuel a little more.
We'll see how that works...

I too have opened the end cap and added disks to mine.
Presently I have a 1 in. diameter hole in the cap and 12 disks.

By running 2 disc less and an open end cap you you will maintain more backpressure to help your low end problem, If you run 8 and it seems fine install the other 2 and see how you like it. The more open the less back pressure and less lower end untill a complete tune can be done. With the Cat still in the head pipe you may not notice much. Doc
