30% throttle?
While in sturgis I was talking to a gentleman tuning bikes and adding performance mods, I was discussing why my bike was a pig below 3000 rpm with my stock 96 with redshift 575 cams and a power commander. He said I had 2 problems. 1 is the decatted header and the other is the power commander v. The pcv piggy backs on the ecu and the stock ecu does not allow wide open throttle above 3000 rpm. where the thunder max does since it is a stand alone. Can anyone confirm or deny. He seemed pretty sharp but his pricing was out of line on the parts.
Bike is a 2010 ultra with decatted stock header, bassini slip ons, stage 1 air cleaner and redshift 575 cams.

I believe most full-featured tuning programs are capable. But why would you want to do that?
Unless you have a turbo system, an increase in throttle beyond the abilities of normally aspirated intake and chambers will do nothing except slow acceleration, decrease efficiency, and load cylinders with useless fuel.

I had a gentleman tell me that is part of my issue. The bike really doesn't like any gear below 3000 rpm. to hold a 70 mph cruise speed I have to run in 5th because otherwise if I hit a small hill the bike will pull down to 65 or less. It really wants to run 80 and my fuel economy sucks.

With that said, I think your mods of cams and exhaust may play a much bigger role then the PC (although I would certainly consider a full-featured tuning program over a piggy back unit just about any day). It seems the twin cams require more back pressure then many want to admit.

I was looking into a 2:1 but I really think my solution is **** can the cams or build a xxx" motor and I am not looking forward to either. I was hoping some knowledge would come in but it appears I made a poor cam choice for what I am trying to do.

Those cams are most, if not all, of your problem. Having the throttle blade not being able to go to 100% under 3000 in your case is not a problem, as a matter of fact that would make it worse. The tuner guy being not very knowledgeable about this probably didn't do a very good tune either so that isn't helping either. He was trying to up sell you big time. The Thundermax is NOT the answer to your issue.
