just installed a GReddy Profec-B Spec II Electronic Boost Controller ... Holy Crap!!!! ... it's like a different car. ... my friend has a nicely modded prelude and we were about equal in power and then I installed the EBC and gave em a little test drive ... knocked him back in his seat it did ... he was very impressed ... I was at a light and a newer WS6 trans am with a raptor hood was behind me ... and normally a car like that should kill my car before the EBC, but I had a quick reaction time and gunned it and he couldn't catch me ... I saw his tires smoke and he was coming up on me fast but he never passed me. ... if you got a turbo and can't afford an EBC at least get a manual one ... it's so much fun and highly recommended
