i had a tuned lucas and was pretty happy with it
i followed JPs guide for the most part then like the guys said alot of fine tuning
but in the end mine was something like;
Turbo wound right in so i could just control it with the fuelling.
Max fueling was at about 180deg and was getting 19 ish psi (apparently any higher or even that on a TMIC can decrease efficiency due heat soak).
Boost comp screw as i understands it, basically controls at what PSI the pump adds the extra fuel so the more you wind it out the sooner it adds fuel so you get more smoke as your not getting enough air till your turbo picks up, I had mine wound all the way in then out some.... maybe 2.5 i dunno it was abit of a compromise but if your careful you can control the smoke with your right foot
I also (I dont know if would suggest it as it caused me a WORLD of pain, frustration and weeks of micro nano adjustments several times a day) but I adjusted the static timing but I WAY miss under stood what a fraction was so went to advance then to retarded and lost the original mark.
it didnt boost right, it didnt fuel right but after too long i managed to get it better than before i started, it was fantastic i gained a psi or so but it just generally felt sharper etc
my thoughts were if your increasing the fuel injection period your surely going to change the most efficient degree of injection so in an ideal world after tuning we would get the pumps retimed by a degree or so.
guys dont shoot me if some of it seems abit.....off, its only to my understanding so far but i was able to pull away from my brothers stage 1 HDI quite nicely
