Want to crank up your turbo game? Wastegate spring pressure is the unsung hero of your boost pressure setup. Without a boost controller, it’s a simple one-to-one deal: a 10-pound spring dishes out 10 PSI of boost—easy peasy. But toss a boost controller into the mix, and boom—you can double that spring pressure to hit around 20 PSI. The trick? Pick a spring pressure that’s half your engine’s max boost goal. So, if you’re aiming for ~20 PSI, grab a 10-pounder and let the controller work its magic.

When you’re reinstalling, don’t sleep on the details: make sure the diaphragm isn’t pinched (ouch!) and double-check that the firing ring is snug on the flange. A little TLC here keeps your turbo humming smoothly and your performance on point. Boost smarter, not harder!
