Inj Duty Cycle Question

I am running a BW and a set of Dynatech headers. Car runs close to 100% IDC on hard pulls. Pulse width and flow rates are stock. An identical car sees IDC of less than 80% with stock injectors.

Any ideas as to why my idc is so high?

If it's running pig rich, it can cause high IDC readings.

Good point. I should have mentioned. Car is currently in SD for VE tun ing. AFR's are reasonable.

I was running 130% with cam/boltons with my stock inj. Now im running 90% with 30lbers... but the car is running good and is tuned good. So Im not sure whats going on either.
