Re: How do you know when its time for bigger injectors? You and I are right at the same HP point and have the same size stock injectors. On some recent runs, I calculated my duty cycle and it was maxing at around 105% (I need bigger injectors) You want to shoot for a max DC of around 80-85%.
Don't have the formula here but search in the computer section. y2khawk posted the formula recently in a thread. You need to log your bank1 and bank2 base pulse width's and then convert them to duty cycle.
Since we're the same, I guessing you're in the same boat as me.

My buddy had a similar setup and ran stock injectors and it was fine. Shoot, it was running too rich and it was fine...2000 injectors. I forget what the injector P/W was...I've heard that 20 is a little on the high side.
