It's been shimmed?
Wouldn't have thought it needed shimmed, that will reduce the travel of the LDA, possibly to the point it won't get full travel, combined with a lot of preload on the spring it would need really high boost to get decent fuel out of the pump.
Personally i'd take any shims out, back off the preload, and take it from there. Will give you a lot more smoke off boost whilst having the effect of allowing full travel of the pin, but then you can keep adjusting preload until you're happy. Oh and watch your max fuel if it's wound up to the point of the idle climbing, maybe back it off a bit until you've figured it out. You don't want to allow the LDa to give max fuel when you're on the limits of an 11mm or you'll get a ridiculous amount of fuel through it
