Overboosting to 20psi!!!! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

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
