the next step up is 30 lb svo's. that's what im running at 396 rwhp(466 bhp). but really you don't have to upgrade till 400+ rwhp. i just went ahead and did it because i knew i was close to that mark and the next few mods i do will put me well over 400. also the 2000 f-body's come with 26lb injectors that max out a hair lower. but the next time you go get a tune look at your AFR chart, and ask the tuner what the duty cycle is on your injectors at redline.

I did injectors on my car when I changed my cam.. You need to hook your car up a HP tuners and see what Duty Cycle you're running. Like I said when I did the cam, my Duty Cycle was 98%.. That means my injectors were spraying pretty much all the time. 108% is all the way open. I bought FORD 42# injectors, tuned them and now my DC is 54%
all mods are in my sig

108% is full duty cycle, meaning that the injector should not be pushed past that point or you could go lean etc. but duty cycle is pretty self explanitory...it's how much the injector is working in layman terms.

and I got my Ford 42# injectors for $125 brand spanking new in the box.. Friend needed cash and was desperate to get rid of them
