Star wheel
 

how far can you turn the star wheel down in the pump will it stop once its all the way down? also does it give much power compared to the increas in smoke?

It will stop when it gets all the way down

yep

is it worth the power gain?

IDK it gives you some more low end smoke and maybe a little power but it results in slower turbo spool. Its really not hard to adjust and can be better used with an aftermarket fuel pin to fine tune. Adjust it, if you dont like it put it back where it was or play around with it some

its kinda strange. it feels like it just moves the torgue ban a little bit.

i didnt notice any more smoke or power with mine. i went all the way down with mine

ya i dont think its much of an improvement.

all i noticed by movin mine was, with it all the way foward it spools faster an all the way back it takes forever to spool

what do you mean forward? all the way in or all they way out? kinda lost me
