Question 2 lean need help

Just got my car on the dyno for the first time. I made 4 pulls, 2 on motor alone and 2 on nitrous. the 2 on motor alone a/f ratio was right on the money i think it was around 12:2 to 1. the other 2 on the juice where extremly lean. What and how do correct this using ls1 edit. Any help would be great.Thanks

12.2:1 is considered rich for your NA pulls. If it was going lean with the nitrous jet the fuel side bigger...

Like Carl said, 12.2 is a little rich. What type of nitrous kit are you use, your mods, and the afr on nitrous. Do you have a dyno graph you can post?

have dyno graph but dont have a scaner. a/f was i think he said 18.0 to 1. the car is a 01' ws6 with long tube headers, off-road y-pipe, slp lid,4.10 gears and a dry nos kit with a 100 shot k&n filter and free mods.
