I got my Pedal Force RS2 with SRAM Rival built yesterday. On it's inaugural ride, it was skipping gears, more like when I would shift up/down, it would lag a bit behind. Even when I'm in the gear I want to be in, it sounds like the sound I would get if I was cross chaining (which I'm not).

Maybe I need to get used to the double tap.

I either, A, need to break in the drivetrain, or B, get my chain/FD, RD adjusted.

Thanks.

i say small tweak to the RD so that it centers under the cog when you shift and isn't slightly to one side or another.

I'd say you need a little tweak to the rear derailleur. The derailleur pulleys need to line up exactly under the cog the chain is on. See: https://www.parktool.com/repair/readhowto.asp?id=64. Just scroll down to the section on "index setting". All you need is a good set of eyes, your hands, and some patience.

If it sounds like it's skipping even when it's in gear it's probably just a simple barrel adjustment.

If it's not shifting well, then some adjusting is needed. Once it's shifting well, you may still have some "rumbling" on certain cogs, but that goes away after a little mileage. I've put on two new SRAM cassettes and had this with both, but man, did I sweat about it the first time!

Or the B screw adjustment.

Once you're ruled out all of the above, if your frame has internal cable routing, make sure the derailleur cables aren't crossed inside the frame.

One minor detail that I missed when I installed my Red group was the proper rear cable routing. It caused all kinds of weird gear skipping. Luckily, I caught it on the repair stand. The SRAM rear derailleurs do not rout the cables like Shimano or Campagnolo. There is a grooved channel that the cable runs in after it leaves the housing/stop before it's bolted down. If the cable is not in this groove, it won't function properly. Not that this is what's happening in your case but something to throw out into the ether for other to discover.

Just got back from my LBS, they fixed it up. Thanks all for the help. SRAM is the shiznat.

+1 to that. I have my Shimano bike on the trainer, permanently it seems. I was on it recently and thought "you know, this isn't too bad. Why don't I ride this on the road?". Then I hopped on my SRAM carbon fiber jobber and realized there's just no comparison - and no way I'm going back to Shimano.

Oh and FWIW, if your shifting acts up again, one small click turn of the RD barrel adjuster will likely fix it. Cables do tend to stretch.
