Injectors?

depending on which injectors you get, they can be a real pain in the *** to tune (no data available to plug into the shitload of parameters).
if you were going to add over 100 dry shot of nitrous, then you might want to upgrade. however, if you're not exceeding 80% duty cycle, there's really no reason to upgrade and you should really leave them alone.
if you have a problem with your stock injectors for some reason, replacing them isn't too hard. you basically just remove the bolts that hold down the fuel rail to the intake, pop off the clips that secure the injectors to the fuel rails, detach each electrical connector from each injector, and pull injectors from the intake and fuel rail. just make sure you get replacement o-rings from the dealership and lube them up with supplied lubricant (or oil off the oil cap or dipstick without getting injectors oily). its hard to see it happen and detect it, but they break easily and will squirt fuel everywhere when they leak. install is the opposite of the above - be careful you don't damage the o-rings (the ones between the injector and the fuel rail in particular) when you push the fuel rail onto the injectors. hardest part is getting back in there... you will cut yourself.

With some minor bolt on mods done, you don't need bigger injectors. '02 cars came with 28.8 lb. injectors. They should be good for a cam only car or mild heads/cam car. It also depends on elevation as well. But you should be fine for what you are doing. Going to a larger injector at this point, won't add any power. It probably would hurt part throttle driveability and mileage more than anything.

You don't need larger injectors. When you do, the best route is to send your injectors to Fuel Injector Connection and have them rebuilt and resized.
It is the most straight forward means of delivering more fuel when you need it. The only parameter I had to change with the FIC mods was IFR, no other parameters needed to be tweaked at all. They are almost plug and play.
