If you change out injectors and go larger than stock, you'll need to have your injector table rescaled. So if you do that (and you dont need to if you dont have modification or plan on modifications) budget for a tune.

stock '99 is 26lbs @ 58 psi.

those bosch 30 injectors are actually 35-36lbs @ 58 psi for an LS1. Are you trying to convert to E85 or something like that?

Fuel injection has improved greatly since 1990. Your '99 comes from the factory with EV6 style bosch injectors. No reason to upgrade

your injectors will support more hp than your engine is making now. unless you want to change the cam and heads and get a tune. leave it alone.
