supercharger questions

i am going to be buying a supercharger soon and will start out by running like 8 lbs. of boost. what size injectors should i buy and should i get the 90mm lightning maf? i will be getting a dyno tune but will i HAVE to run premium or can i get a tune for regular?
 
I have 42lbs in my 96 Cobra with NO FMU. I would highly recommend NO FMU. My car runs and idles perfect. Crusing speeds....perfect. I have a 255lph in tanks pump and a 255lph in line pump. 8lbs will make your car fast and reliable. The stock bottom end will hold up fine with a good tune and good fuel. Those are the only things...(if bad) that can kill a bottom end.
 
at least 42 pounders. it all depends on how far you wanna take the car. i like the lmaf.
im running 42s, focus and BAP, lmaf and ia, and stock tank.
I am running out of fuel now on a safe tune.

run the higher test to be safe :flag:
