The general consenus is that you want a wider LSA so you dont bleed boost off, but remember boost is not an indicator of power, airflow is. I think that you should just buy the cam with the street manners that you prefer, then strap on your blower. You can always up the boost with a new pulley or different wastegate settings if you want that set amount of PSI. Simply put, a big cam @ 10 PSI can yield more power than a stocklike cam @ 15 PSI, its all about airflow. Why, because the bigger cam can push more air through than the smaller cam. Also keep in mind that a bigger cam will bring your compression down more too, which is good for boost to prevent detonation.
This has been debated a good deal around here already.

With a cam like those you will bleed a lot of boost out from the cams overlap, so you will have to spin your turbo faster to make the same amount of boost that you may have been making with a stock cam because the stock cam does not bleed boost because it has very little overlap.
Most people with FI like it because of the streetability since you dont really need a big cam to make good numbers, you just turn up the boost, thats why most go with a timid cam.
