help identifying injectors?

[luv2whelie]

I'm wanting to order a new chip from Turbotweak, and know my cam, stall, turbo, etc, but only know that my injectors are 50lb. This number is engraved on the side: 154 45/5 624. Does this mean anything to anyone? I suspect that the "154" is for WOT (stock + 20%), but have no clue on the rest. Help?
Thanks!

Sorry for the delay; I've had computer issues I did figure out my injectors, and got a new turbotweek chip I've eliminated my erratic idle issues (another of my posts awhile back) too! Mike Casteel has been helping me with my car, and it turns out that what I thought was a valvetrain clatter was several exhaust leaks where the exhaust manifold on the passenger side had been over-ported. Got it welded up and the clatter went away PLUS my idle stabilized! I think the pressure was leaking off, causing surge in my turbo maybe? or erratic back-pressure? at any rate, it idles great now. I installed a new wastegate puck this eve, and hope to get my downpipe back on tomorrow so I can get back on the road

Most likely, the leak were messing w/ the O2 sensor readings...
