Well, I finally had my first day of driving with the new wideband O2 sensor/gauge setup. No more crazy light show like you get with the autometer gauge.
Looks like I'm floating right around 14.6:1 AFR during idle and cruise. But at WOT, I start out at about 13.2:1 AFR at around 3000 rpm then it richens up to about 11:1 AFR at 5000 rpm. Looks like I need more airflow at the higher rpms? What do you guys think? I thought I was running lean at WOT with the injectors that I have but I guess not.
Here's my setup:
95 XJ, AW4
Hesco 4.6 stroker, 4.0 rods, forged pistons, 9.42:1 comp ratio
WJ intake manifold
Borla header, hiflow cat, and magnaflow muffler with all 2.5" pipes
stock 39 psi fuel pressure
Accel 21# injectors (flows about 20#/hr at 39psi)
Airaid cone type filter
stock throttle body
msd ignition, screamin demon coil
So you think I need to work on the intake system?
Any input would be appreciated.

By the way, I posted this on the yahoo stroker group too. Just want as much input as possible.
