Hello, I am trying to get all my ducks in a row before starting my tuning. I am building an 04 4.8 silverado 5spd with a custom built forward mount turbo system, I have a set of trick flow 55# injectors (http://www.trickflow.com/partdetail....5&autoview=sku) and was wondering if someone could give me a run down of where and what needs to be done to tune these in. I am also wondering if the maf will be able to handle/accurately read 12psi of boost or should it just be eliminated? thanks. Eldon.
