Default Injectors

Industry standards say NOT to exceed 80% duty cycles on your injectors--I have gone as high as 85% with no issues
I would 1st have someone data log your injectors to see where they land at WOT
What is the stats for the stock injectors for a 2003? Are they over forty pounds? I'm still learning about the injection system and with mine having lots of miles on them I'm wondering if I'll benefit from new injectors. But when I look up injectors for my car there is a plethora of ones that fit all with different pounds. I'm not an idiot but I'm not knowledgeable enough to make a decision on which ones to get for an engine with a cold air intake and exhaust. Thanks for any help you can offer.

I haven't done any real tuning with it yet, but I was able to use our stuff (in conjunction with Tuner Pro and a $40 OBD2 cable) to disable CAGS in the PCM software on my 02Z.

So we have the beginnings of a new answer to the question in the subject line of this thread.
