Well, I decided to do a 4th gear pull today to see what my boost gauge was reading after I've fitted the JPerformance Manifold and the Blitz Decat.. Acording to my gauge (which isn't the best) showed that I peaked at exactly .7 bar but then dropped of to .6 further up the rev range.. Is this normal? What could cause this? My setup is: Standard CT9 Turbo JPerformance Manifold Blitz Decat Blitz Nur Spec Exhaust RW Developments Relocated Filter Standard Actuator Autogauge Boost Gauge Greddy Type S BOV Any help is appreciated .. Matt.
