Throttle oscillating?

Hey folks,
Is anyone out there experiencing throttle oscillation when trying to cruise at constant speed? I recently installed a p3 gauge and a helix intake, and I'm wondering if I created a boost/vacuum leak.

Example: cruise control on at 70mph, level highway, throttle guage fluctuates between 22 and 24 constantly, resulting in noticeable jerking.

Thanks for any input!

Sounds like you have a leak. I'd check intercooler hoses

Update: Turns out it was 2 bad primary O2 sensors... Related codes 2C39 (driver-side) and 2C3A (passenger-side).
