I got my tuned so i just have a haze of light grey smoke for a bit till the turbo spools then its gone but im still on stock injectors (for now ) so i cant comment on adjusting you setup for DDPs.
i run with no plate and can accelerate at a pretty fast rate with only a little haze.

So, if you lost mileage by sliding the plate forward, the logical solution would be sliding it back little by little to find the happy medium.
got a good point if you only moved that and fuel mpg went to crap slide back til you reach a point of satisfaction

you have the three big things as listed below. play with them one or two at a time and get a happy spot. you take the afc and set it to fuel at a certian pressure like some have done with shop air and a regulator then you can play with the smoke screw and fuel plate. i would also check and see if the arm is even hitting the fuel plate if not you adjust that so that it will follow the contour of the plate to fuel like you want it too.

1. smoke screw (back of afc housing)
2. star wheel
3. fuel plate
