I am no LS tuning expert, so I hope someone who is can chime in. Do you have a wideband? It it really lean? Is it only out of the hole that it lacks power? Where does the converter flash to?

If you watch the log , you can see the AFR reading off the wideband. Yes it really leans out... And off the brake the converter flash's at 3400 . Exactly where it's supposed to. But the car is gutless trying to launch it off the brake.
