425-450 hp, depends on what year you have (98, 01, 02's came with 28lb injectors, 99 and 00 came with 26's)

Get a diagnostics program and check to duty cycle on your injectors, if its close to or over 100% you may need to step up.

with your mods your fine unless you wanna spray a dry shot or something

450rwhp and they are usually max'd out. You might also want to throw a new fuel pump in as well.

RC's calculator tells me that your 28Lb injectors can provide reliable fueling for 460 Flywheel HP(~415 RWHP) at 58 fuel PSI, .45 BSFC, with the injector duty cycle at %80.

When you exceed 80% DC, it's time to upgrade
