ok right now im running all the bolt on's minus the intake manifold. just wondered when it would be helpful to upgrade the injectors. like what to upgrade to, waht all needs to be upgraded....really and info on this stuff please cause i really dont know anything about it. would it help to upgrade with just bolt ons? i was thinking about a cam in the future but didnt know. any advice please! thanks

 

No your fuel system is just fine til you get up to about 450rwhp. Then I would look at replacing injectors and fuel pump.

ok what about replacing the stock injectors with a new one, do the stock ones get old and nasty? or nothing to worry about?

 

No they will last some time. Don`t be concerned with it till you start to max them out.
