MG ZR ZS ZT Technical - ZR160 hidden power?

hi, i have recently changes from a 03 ZR 100 Diesel to a 54 reg 160 with 3500 miles. i make the following observations:-

the idle seems quite uneven - light flywheel maybe?
seems very easy to stall without 'blipping' the throttle
no torque to speak of
lack of power until well past 4000.

i doubt if has 158 hp even at the redline and under 4000 it seems as flat as a witches T*T
MPG 35 if i am good and keep it below 80 over 80 it is more like 30mpg

is this normal as i find it hard to believe that MG would have made an engine like this.

could the V V C be locked on ?
thanks

Does'nt sound right, the idle should be smooth and the torque below 5000 should feel like a normal 1.8 K series.
Stalling should'nt be easy to do either, i would suggest getting it to a specialist with the correct diagnostic equipment to run checks.
