We dive into the Silverado and swap out the low pressure spring in the Tial BOV for one with a little higher pressure in the hopes of getting a little more boost in the lower RPM range. On top of that we toss together a boost leak tester and check to see how many leaks we actually have. Spoiler. A few.
Thanks to the guys over at the Max Effort YouTube channel for loaning me a AEM TruBoost controller!
