hey guys, my car's ECU is not controling the wastegate solenoid anymore, so i only can run on what ever the wastegate spring pressure is, so any advise? ECU replacement or EBC? or MBC?

any advise? and what is those EBC and MBC going to effect my car? wanna hear from you. thx.

I would recommend the Greddy Profec 2 Electronic Boost controller. Difference in turbo spool characteristics, which translates into smoother turbo and vehicle operation, and better drivability. No boost spikes!

cool, thx alot, and one more thing, your are location is in Hayward? are you the one bought a STi exhaust from me before? blue 04 wrx?

Uh..Don't think so. It was probably someone else.
