Whats the reason for getting new injectors? If you've got a couple that aren't up to spec just replace them with stock size, reason being, if you plan on S/Cing or running NOZ in the future you'd need even bigger ones = more expense.

i just want to get them because i just got a new intake manifold and spark plugs and wires.. plus everything in the engine like the spark plugs and wires were stock ever since the car came out of the assembly line. the guy before never changed anything. and i doubt ill ever get a S/C or NOS.. all i got on it right now is slp lm1's, x pipe,cai. 75tb,75mm plenum, getting pulleys next week and to top everything off i want a chip and injectors.

There is no power gain going to a larger injector and you will need a tune. I would look into having the stock injectors cleaned and flow tested.

You might want to buy an adjustable fuel pressure regulator,keep the stock injectors and adjust the pressure a little higher....

This is not something you want to do unless calibrating the computer for the new FP setting.

Simply adjusting a FP regulator is the "old school" method of "tuning"

Anything done mechanically must be compensated for with the PCM. If you need extra fuel, add it through the specific points within the computer.
