just installed option 3 and FPU. when test driving, there's a whistling noice coming from the intake after 3000rpm. any one with the same problems and knows how to get it right?
well, in fact i can. because when inside the car, most of the noices from the engine bay are filtered. however the whistling is of quite high frequency. that's why i can hear that whistling more clearly inside the car.if you cant pin point the same noise you can hear during normal driving...with the hood up...someone else should do the listening...you may have hearing loss, or just didnt try hard enough...or something else is wrong with your 6 that is making other things too loud.
something that loud ( you can hear during driving ) you should be able to find.
