Engine is "choppy"

Not sure how to exactly describe the issue I am having. Truck has Spartan 300 EL tune, 5" DP back exhaust, and everything else is pretty much stock.

Truck starts great cold and at temp, runs great except for about the 2100-2200 RPM range. While in that range truck stutters? is choppy?, feels like it is missing. It does not matter the road speed only the RPM. I can slow down or speed up and it clears right up. It does not sound like a big deal with it only happening in such a small window but you would be surprised how much driving is done in that range.

Has anyone else run into this problem and if so was it a tuner issue, fuel, trans? I'm just looking for a good place to start.

Thanks in advance.

I'm know some tunes had some surging in that range. I'd e-mail spartan or contact Jeff on here I'm sure they will point you in the right direction
