Stock Injector Duty-cycle
Did a couple logs with Hp Tuners software the other day. 3rd gear pull to 6k rpms. Noticed IDC was over 90% at 6k rpms. The car has only a roto-fab intake on stock tune. Is this normal? Inj pulse-width was over 16-18 milliseconds

Sounds about normal.
Log commanded EQ and you'll see that COT fueling is adding fuel. Here's a screenshot of mine when stock.

I was wondering if i needed to go ahead and get bigger injectors. I do like my warranty. But its hard resisting the mod bug. How do you like the FIC 95's and LS9 cam?

No problems. The cam idles and drives great, doesn't stink the garage up when idling, and makes 25rwhp more than stock. Plus it was what ADM recommended when I talked to Andy about my goals. So far, so good.

I have headers, Roto-Fab, and ported throttle body and tune. My duty cycle was in the mid 80's.

I'll be going to those once I upgrade the pulley's. I'm really looking forward to that upgrade!
