Maf Air Flow Sensor

[knakkers]

G-day guys
After a bit of info regarding Maf air flow sensor
Is somebody able to please tell me where the Maf air flow sensor is situated on a GU 2002 ZD30 engine??
Reason i ask is because, ive started to develope a little bit of a flat spot in acceleration around 2000RPM in 2nd, 3rd & 4th gear, just before the turbo kicks in while accelerating up hill.
Ive been told that the sensor could be dirty & give it a bit of a clean, that could be the cause of the flat spot issue. But i dont know where it is situated.
Or does anybody have any other ideas on what could be causing the slight flat spot???
Any advice would be greatful thanks.
I have ran a bottle of diesel injector cleaner threw the tank to see if that will fix. No luck.
I have recently fitted a Redback hi-flow 2.5" exhaust system & a Tunit diesel performance chip, (which has made a massive difference in torque & power) but at the same time inhanced the noticable difference of the slight flat spot.

Thanks Threedogs. i thort that might be it. Where the wiring plugs in?? Problem is i dont have a torx bit to fit.
Strangely, i used to work at Kincrome tools & i have every tool under the sun except that size torx bit "Bunnings here i come"
