Here we go again...
I've noticed recently, my D2 auto is lacking in power. It had a new fuel pump a couple of months back and a gearbox oil change (Well, half of it, as we know how it works). All seemed fine after. It started to get sluggish especially on hills so I changed the fuel filter and gave the wastegate a spray and a good ragging back and forth for good measure, which improved performance somewhat. However, in the last week or so, it seems to be struggling. The revs seem to climb higher to squeeze power from the engine. The gearchanges apparently happen at the right road speed but it feels as if the engine is working harder to get there. I get TC lock up at 54 mph as I should and under lighter acceleration the gearchanges are normal. On harder acceleration it lacks power and as I said, revs higher than normal before changing gear.
Any ideas?
 
No cat. It's a 2001 10p engine. Since January, it's had head gasket done, recon turbo, fuel pump, 2 fuel filters, 2 air filters, drain and top up of gearbox oil but it now seems to need a heavy right foot to squeeze power out of the engine. I'm thinking boost leak but all hoses and small pipes to actuator etc appear to be intact. Would a busted intercooler give these symptoms? It has seen better days.

Yes if its leaking.

I've also noticed a bit of smoke on acceleration, only at night in the headlights of a following car. Not enough to be noticeable in daylight.

Sounds like its burning fuel due to the lack of oxygen throwing out the air/fuel ratio the engine will run rich
& you burn more fuel hence the smoke.

I think that's a bit of a fallacy. Inlet hoses after the turbo are under internal positive pressure, therefore should 'inflate' even if delaminated.

Sufficient of a fallacy for it to have been mentioned umpteen times on this forum by respected posters, and even you have said "after the turbo". If a hose delaminates, it can let a flap of material float which then can catch the pressure and form a partial blockage.
But then what do I know?
