Thanks for replying. Perrin's Stage 2 93 Octane map. Mods are Invidia Divorced Wastegate cat-less DP mated to optional SPT 3'' catback using Grimmspeed Adapter to avoid any leaks, Kartboy Front/Rear Shifter Bushings, Cobb Heatshield and that's it.

I was running the Cobb Stage 3 93 Octane map while I had the stock airbox and was seeing up to 19.1 PSI and no hesitations/hitches. I added the intake in hopes of a colder intake charge and slightly more aggressive sound. Since the issue w/ low boost target on this map and hesitation happened right when I installed the map I'm pretty sure it's not a boost leak. As someone said possibly it's the ECU getting used to the map since I've probably only gone through half a tank of gas w/ it?
