As per title, really, as ive not got a clue!

Ive never had any dealings with them, so its one part ive no idea of, so, teach me please!

Just the simple cheap 5th inj setups like you see on RS Turbos etc.

How is the fueling regulated?

Does it pick up on boost and rpm and go from there, or just boost, or?

Do you have to use a certain size injector or can you use even big fuckers if you wanted?

How do you adjust it?

What they cost?

How, well, everything, ive never looked at em before!

Cheers in advance
