Im looking to have a car make decent power while still maintaining the stock fuel injectors and fuel pump. Thanks in advance!

Maybe it's just me but I dislike philosophical bantering.
What do you drive? or want to drive?
For example (and personal experience)
an Infiniti Q45 2002 & newer: for several yrs at the infiniti forum guys tried everything to get more power. chips, cold intake, exhuast mods, all the possible bolt on stuff. Despite the manufacuter claims, NOTHING, I mean NOTHING imporved performance. 3 reasons: 1. the engine was pretty tweaked from the factory 4.5L 340hp (in 2002). 2. the ecm chip was designed to compensate for any changes from stock. 3.........lost my thought.
a V8 mustang. There is alot of room to make increases from the stock setup. THe engine design (obviuosly I'm not talking about the cobra paks etc)allows for alot of improvement.
It really helps to discuss in the framework of a specific car or a couple of cars.
