just organised hks boost controller,with it off car will on full throttle rev to red line with no noise,with it on at full throttle it will rev to red line at boost up to 14 pound,but after 3 grand at full throttle i get a noise like a rattle or fast clicks,but car will continue to power on,at half throttle i havent heard the noise. was fine on the dyno couple days ago b4 played with controller,i read a few days ago someone explaining breakdown in the COIL PACKS,i think this maybe happening to mine,at first i thought the turbo could be on way out,but shouldnt it make a noise at all revs if on way out,anyone know what may be,if coil packs does anyone know exact details of how to silicone up
