03 350z with the powerlab turbo kit. Car is sometimes hard to start but when it starts it runs smooth. Upon driving if I give more that 1/4-1/2 throttle car acts like it back at idle and won't go anywhere. Car is throwing code saying car is running lean. Wideband is staying in the 14-15 range then when I slam the throttle down shooting up to 22. Been doing this for months now. Haven't played with it too much just been driving my other vehicles but I miss driving the car.

 

WTF!!! STOP DRIVING IT! You need to get a dam tune! I'm so surprised you haven't grenaded that motor with AFR's in the 20 at full throttle.

 

Definitely the only way to fix this is with a tune.

 

Is this a joke?

 

Lord Jesus this can't be real lmao

 

No it can be. Most likely he's running crazy rich. If you run rich enough, the wideband will read straight lean.

Otherwise at 22 he'd have detonated that thing into oblivion.
