A boost leak tester shouldn't be more than 10 bucks to make. I'm amazing that your car is one of the more modded cars in the area. Austin, MN must not be much of a tuner area
Boost leak testing shouldn't take more than 5 minutes. In fact I'm pretty sure you could have pressurized the system in less time it takes you to start and view this thread. Why not just go find out exactly where the leaks are instead of just guessing?
