So I’m working on getting MY17 tuned and I’m struggling to figure out an issue. Tuner wants to wait and address the issue post tune but I don’t feel that’s the best option..

Mod list is simple...
MAPerformance turbo back (catted).
MAPerformance Intake
Boomba BPV

car idles perfectly.. I have narrowed my issue doe to cruising. Say on the highway between 2000-3000 rpm if I’m cruising the car will start to “surge” or “pulse”. As it’s doing this my vacuum gauge will fluctuated around 5psi.. Now if your on a slight incline or decline it will stop. Only on a flat steady cruise... Ive done some leak searching but coming up Short.
