Default Dry shot going way lean off the line. HELP!

I have a compucar dry kit with all braided stainless line and a single .073 jet. It bogs bad and goes way lean for about 2 seconds, then it hauls ***. How do I tune out this extremely lean spot? I doesnt matter what speed I'm going, its just the first 2 seconds of spray. Once it gets moving the O2's read a fairly steady .850-.875. I wish santa would have gotten me a wideband. lol

What size injectors are you running? It's hard to get a accurate reading of the AFR at WOT with stock narrow band O2's. A Wideband is a must when spraying.

I have 38.5# injectors. I normaly run 60% DS N/A and I was running 77% DS with N2O and richer PE.

with it bogging you sure its not adding too much fuel? Lean should actually make Ping or HAULASS. rich normally is bogging.

there is no ping, but the O2's drop to nearly 0 and after the bog is gone they go to a steady 850-875.
