Default Injector size question.

I just put in a TR224 cam. While tunning I was told my injectors were at 101% but I was not running out of fuel. I have a 2000 SS. I think the injector size on the 2000's is only 24lb. My question is should I upgrade my injectors now? I plan heads in the future & possibly Nitrous.

They were at 101% duty cycle? I personally would, especially if you plan on doing more modding down the road.

SVO 30lb are popular for mild setups

Is there any chance you might go with a dry N2O kit down the road (buying stuff twice is a pain!)? If not the 32lbers will be good.

If you might go with a dry kit, depending how big of a shot it is, you might want to look at the 42lbers - 60 lbers.

If I do Nitrous it will be a wet kit. Probably a TNT kit.

I run 42lbers and a walbro pump N/A. Get the SVOs, they are rated at 48 p.s.i.

Shouldn't my stock fuel pump be good? Do I really need to add an inline pump? even if I run a 100 shot wet?

No, not with a cam and bolt-ons. I also suggest not going with an inline fuel pump. Do it right, go with a intank pump kit, like the Racetronix kit. A link to them:

Go with a intank pump. the inline is only going to pull the amount of fuel that the intank one can. The Racetronix is a good route. I went with a Walbro intank and Caspers Fuel Pump Hot Wire Kit.
