The problem I am having, is for lack of a better explanation, is my RPM seems to fluctuate at 1750-2000 RPM. When cruising about 40 at that RPM range. ONLY occurs fully warmed up. Idles like a champion. Pulls HARD.

The WB shows a swing of 14.0-15.6. Vac stays rock steady. Car doesn't feel like its missing/bucking at all, just feels like it cant stay decided on the RPM.

I thought it was my CeddyMod big maps not set up correctly, so I removed them, but the problem persists. My spark plugs are gapped correctly, checked 3 times. O2 sensor brand new OEM

I was thinking maybe a boost leak (but wouldn't that be a problem at all RPM/driving conditions?) or a TPS problem. What says the collective?
 
Check your fuel pressure, it might not be holding a steady pressure when cruising and also check ## injector connectors for being loose
