Lack of boost, lack of fuel... bad ground on ecu, bad contact on ecu plug...
or 1.8 PG1 fitted
Mine goes up on 5rd gear from 1500 with no problem. (even when set it to stock boost and fueling) . When accelerator pressed to floor it response with quick boost building (5 to 16 psi within a 1-2sec.) and drives away
here you got boost response on stock boost settings and fueling (just EGR removed, with rubber pipes)

Hi Winu, thanks for your thoughts
I admire what you have achieved with your L Series Freelander.
Hopefully I've got the right gearbox! I suppose they look the same from the outside - would just be different gearing inside. I've had the car about 4 years now and its always been the same - at the time we got it I thought that it was lacking in power/refinement at low revs when I slowed and dropped gears to go round a corner and discovered it would not pull from anything under 1,500 revs - eg I needed to be in 2nd not 3rd. I just thought that was the way they were and haven't investigated it. I'm very happy living with the car the way it is.
But if I can make it even better then that's a real bonus
1,500 is a 'magical number' for my engine, from there all the way up there appears to be plenty of power and its very smooth.
Occasionally at high revs I'll get a lot of black smoke - if I try to reproduce it, it doesn't happen, just occasionally at high revs. I have changed the air filter which reduced the occurrences a lot.
I don't think there are any issues with fuel supply to the engine. If I had ECU connection problems, would they not appear throughout the rev range? Maybe I need to service the air supply/turbo system.
TBH other than rebuilding my IRD, all I've done to the car is general servicing. That's all its needed in the 4 years - plus the ABS modulator that a local Rover garage/breakers supplied and fitted for a ridiculously small amount of money! Its been a really great car - this weekend just gone it did another 1,000KM trip in reliable comfort
So maybe I should repay it by checking the air system - and maybe fitting one of those boost gauges to make sure it keeps performing!
