while on the highway doing 100km/hr at about 2500rpm on neutral throttle i hear a high pitched noise (i can also get it in 4th at the same rpm). as soon as i go above 2500rpm the noise dissapears and changes to the normal turbo spool noise. i've checked for leaks in the intake but didn't find anything. I've checked for play in the turbo bearings and things seem fine. is this just normal for a nav with a snorkal and i'm just being paranoid? i still have nissan factory warrenty till march 2010 and i'm wondering if i should bring it in for them to have a look at? might have to return egr back to standard but
