OK I have a custom turbo setup with a HKS wastegate. And for some reason I can't turn down the boost? Im hitting 10psi really quick and sometimes 15psi and im having to let of the gas....Maybe I have it hooked up wrong?? Or is my wastegate staying open or something? It seems to be running good its just boosting way to high and im only stage 1 right now cuz I haven't got the piping made for my starion FMIC...anyone have any ideas???

Make sure your wastegate is actually getting a boost signal. if it does not, it will never open and you will boost to the limit of your turbo.
Beyond that .. Make sure you have a low enough rated spring in your wastegate. a 7 pound spring is roughly enough for 5-6psi at the manifold. If you have a 15lb spring, it'll want to boost to 15psi.
If you know you have the right spring and you can verify that you are getting a boost signal, your wastegate may be damamged.
let us know what happens.

OK well Im pretty sure I have the wastegate hooked up wrong and im not sure what pound spring it has in it. I dont know if you are familiar with the HKS wastegate but it has two ports on it...it has one on the top and on the side and I wasnt sure on hooking them up?? Right now I just have a line going from the top of the wastegate to the turbo..do I need to tee in a vacuum line or do I need to hook something to the other port?? If you can help me out I would really appreciate it...this is the last thing i need so i can drive my car cuz i haven't been driving it since its is boosting so high.

Use the port on the side. My wastegate is like that, too - there is a port labeled "vaccuum" on top, but the port for boost is on the side. You are actually boosting your wastegate shut as it stands now.

OK cool man thanks!! Im going to try it as soon as i get home...do I need to hook a vaccuum line to the top?? Also do i just hook the side port directly into the turbo? Thanks for all your help!
