Can't find a set of injectors!!
I cant find a set of new fuel injectors under $300 for nothing...
I need a set of 22 lb injectors badly, and all I can find are 21, 23, 24, and everything else, but not what I need....
I need a link to some kind of aftermarket injectors, im about to go crazy.
I would just go to 24 lb injectors, but I dont have the money to have the chip re-tuned.

21lbs are just 22lbs injectors at a lower pressure reading. They'll work fine. 23lbs are either 22lbs at a higher pressure, or 24lbs at a lower pressure. Get the 21lbs and you wont have to reburn the chip.

Define modified. A custom chip will benefit any engine that is changed from stock. But the factory tune can usually handle bolt-ons. Its a camshaft and head swap or larger injectors that will give you trouble.

MSD Ignition
Edelbrock Headers
Bored .30 Over
Comp Cams .500/.510 Lift Camshaft
Ported, And Polished Heads
Ported Intake Manifold
Flat Top Pistons
Custom Burned PROM
ACCEL 8.8 Wires
Custom Porting To TPI Plenum
K&N Air Filter
The engine only has about 2800 miles on it, it had a complete tear-down and rebuild just under a year ago. About the only thing original is the block....and the injectors
There has been a couple other things done to up power, but those are the actual "mods" to the engine

Who did the custom prom?
Do you have an adjustabe fuel pressure regulator? As I said, you can use the 21lbs with the pressure at 42-46lbs, or the 23lbs with the pressure at 38-42lbs.
