boost increase without boost controll

[climaxsr20]

hi guys. well i dont know but i put in my boost gauge and i took my car for a spin and i was running 14-15psi with out a boost control. did i do something wrong or is it okay for that to happen? i have talked to jeff from heavythrottle and he told me to just take all the pipes out and redo them. give me your opinions? thanks.

When you run an open wastegate you will get extremely high boost. Check to see where you got the vac signal for the wastegate.

i have the wastegate vac line plugged in right after the intake filter/maf

you need to hook the vaccum line up to a pressurized part of your piping. The hotpipe is a common source.

This should be hooked up after the turbo, like J-Spec said.

If your wastegate is hooked up, then it will run at what ever the spring weight is. If it isnt, the turbo will produce as much boost as it can. I know this bc my screw came out of the vac nipple on top of my wastegate and I denotated yesterday. If you have an external wastegate, that is.
