Noob question about boost contoller/ wastgate relationship
Ok so how does a wastegate and a boost contoller work in conjuction with each other. If I have a wastegate with a 14 psi spring and a boost controller set at 12psi, what would happen?

Your car would boost 14psi. The controller can only go as low as the WG is set for. If you want lower boost applications then get a smaller spring for your WG.

So if I had a 14psi spring and wanted 16psi I would have to intall a 16psi spring? Or could I use the controller to achieve that 16psi. I really don't understand why you would need both. Sorry just a little confused.

you can run higher psi than what the wastegate spring is but not lower, usually u can run about double the psi than the wastegate spring is.

Exactly...the boost controller will adjust your boost levels as high as the boost controller will allow and as low as the WG is set for. You technically could just get a WG, but you would be limited to only what the WG would be set for...no more, no less.....just the spring setting.

You don't need both of them, but using a weaker spring and a boost controller gives you flexibility. Say if you want to run lower boost in first gear to help traction, or if you are aiming for a certain whp number in theory it will allow you to precisely control the boost to get to that power level. Another reason would be if you wanted lower boost for daily driving but then at the track want to run higher boost.

Okay, so the boost controller isn't required unless I want to run a higher PSI then what the spring is.??

correct. A boost controller does exactly what the name implies...it controls boost levels...so if you do not care about adjusting your boost, then you can just use a WG. Get a decent one though so you won't have to worry about any serious creep or boost leak.

Not to add more confusion, but depending on what engine management you use, you don't need a boost controller. I'm going with AEM EMS and one of the things it can do is control boost, as long as you hook up a boost solenoid.

Tial is the preferred brand around here, it's very popular and proven to work well.
