ok. with a custom kit boosting about 6psi - 8psi whats the best way to go for fuel mangement? This is for an LS and not looking to spend alot. Just need it reliable for daily driving, and street boosing, no high speed boostin.

 

get greddy blue box for B series motor with some 310cc and you'll be fine. For 50-70 for the blue box you can't beat that.

if you want to you can get the common 12:1 fmu + inline fuel pump OR intank fuel pump + missing link and your ready for boost. 6-8psi is nothing you'll be fine.
I don't like the FMU route mainly because of all the stress it puts on the stock fuel lines and components. I would only go this route for 4-6months max.

 

if i get the blue box, will i have to exactly get the one for the LS kit? or would the others B-series ones work fine too?

 

It depends if your LS is OBD1 or OBD2. the blue box is only for the OBD2 (92-up?) Ls.....

blue box are mainly just d and b series
ANY b series box should run nicely. Sohc blue boxes should work but from talking to other members who ran the sohc blue box on ls motors they ran leaner

I belive the blue boxes have certain fuel maps already for each motor.
Even though you use a B16/B18c blue box you'll be fine as long as you get some 310cc injectors cause that blue box is caliberated to idle and pass smong with it. It wil ruch richer on your LS but thats better than leaning out.

blue box can only be re-wired to OBD1 or OBD2 ... and will not work on OBD-0 cars.
