exactly the same as mine, can be heard on idle, part throttle i can hear it but its no-where near annoying or embarresing on my car, its a super cool sound, proper mecanical whizzes and whirs...

so tom your install is complete, your just adapting this thing at present, have you had chance to proper;y t/c off 1st-3rd all out yet???
