These engines do produce there power up top, it's the way it was designed, to have similar chartaristics as a gas engine. You can't get much power below 2000 rpm, I think peak torque is at 2800 rpm on these. The NA intake seems to help with the lower end.
If I pin it in first without easing on the throttle for first few moments, I'll leave a pretty healthy cloud, but that seems to be the worst of it. I believe I backed off on the LDA as much as possible but I will re-investigate. Going more than a third throttle or so in 2nd and 3rd below 2k (especially when cold) will also leave some light grey haze behind me. My eventual goal is to have it be smoke free, but I'm satisfied by the improvement for now. First gear smoke is annoying as I live in a hilly area and getting moving from a light inevitably leaves some haze behind me. Ideally I would like to be able to drive it without having to compromise power for smoke in some situations.
