Overboosting to 20psi!!!!

[roel03]

I just installed my boost gauge yesterday and when doing a pull boost seems to top out at 20PSI. I have a t25 setup with stock wastegate on my ka connected to my intake manifold. Turbo does not smoke but pulls hard, and engine runs awesome. The car is Enthalpy tuned. Sunday I ran it at a full AutoX without a hiccup, but just noticed how high the boost pressure is.

Shouldnt it be only 7psi? How can I get it back down? MBC? I dont really want to use that much money on an EBC as a couple track days are coming up. Any links to a good MBC? This is for reduction, not to increase

make your own manual boost controller. there should be a write-up around here.

Will that bring it down to my desired amount?

I would check your wastegate actuator first. On my T28, untuned, no boost controller it never went past 15lbs.

You can't lower the boost pressure with a controller, only raise it. check the actuator, and the line going to it. it should just go from the compressor housing anyway, not the intake manifold.

Make sure you have your vacuum lines hooked up correctly. Sounds like you have them hooked up wrong.

Will check it in the morning.
