Me thinks you've either something wrong with your car or it ain't a standard ZT oil burner.

50-70 mph in 4th: ZT CDTi = 8.0 sec; ZT 131 CDTi = 6.8 sec; ZT 260 = 5.5 sec.
Ah...I didnt mention it doing 50-70 quicker in 5th than 4th,BUT it does 50 -70 in 5th as stated in 6secs, 50-70 in 4th is slightly quicker,the fact the diesel doesnt rev very high doesnt help in 4th,over 60 in 4th its just screaming to be changed up,nothing really special about mine,like most diesel ZT owners who read the forums you soon realise a few cheap mods release a lot more power,bigger air intake,egr bypass,better air filter and best of all roverrons tuning box,only 150-160bhp but almost as much torque as the 260 and 45mpg easy,still want a 260 though,just for the noise
