Thanks to all for previous technical help (especially Steve). Question on injectors. Assuming the ECU puts out a specific dwell signal to the injectors at a particular RPM/airflow signal will higher flow injectors increase the AFR??

Since my car runs without an O2 sensor signal I assume I'm in some sort of "open loop" mode. According to my AFR meters I'm running almost right at Stoic (14.7??) and that's probably too lean for good power.

I'm looking for a way to get more fueling at higher RPM.

Thanks

Assuming you have a fuel press regulator somewhere in the system, have you tried simply bumping up the fuel pressure?

Higher flow injectors = bad/illegal

Adjustable fuel pressure regulator = good/legal

Assuming the same opening time for the injector, the fuel pressure bump should put more fuel in the mix and cure your problem.
