The ALDA has no effect on injection quantity until the turbo starts to build boost, it has no effect on injection quantity at idle and very little effect at low throttle positions.

Thank you .
The exhaust some -looks- black to me, it only puffs a cloud when I accelerate off idle or am moving slowly in traffic andget the chance to speed up .
I had the engine re sleeved and so on less than 20,000miles ago and one cylinder has slightly lower compression than the rest, I hope it isn't oil smoke
.
Because it doesn't emit smoke every time I accelerate off idle I'm won dering what it is .
It's my daily driver and I'm now retired , no longer have access to a full shop with leak down testers and the air supply to operate them .
Fuel economy has tanked of late, down to 22 MPG's, I can't stand that .
