Hey everybody,
I recently flashed back to stage 1 after going stock for a bit and upon a wot pull I noticed lots of smoke behind me and it went into a half engine light. I thought huh nice to be back to tuned life. I then was driving a bit more and noticed any acceleration with boost would cause the car to buck and slow down after I let off harder than usual. I took a log and then saw 234 afr. What do you think is the issue. Could it be cheap remanufactured injectors, failing hpfp, I'm not sure. Anyways take a look at the log and let me know what you think.
Best,
Sean

234 afr is normal for decel with no throttle input.

Can't really see any issue here. But it's only a short 40% throttle run in 2nd gear.

So half engine light? Did you read codes?

Some injection miss calibration codes but nothing else, they are coded tho through protool.
I did not know that was normal thanks

20 seems to be normal not this

your afrs are normal, once you are off the gas it should go to 234, that means injectors are shut. if it stays at 20 then you have injectors leaking. 20 is NOT normal.

Read the codes?

You can pull the plugs and see if they are wet/smell of fuel to see if injectors leaking.

Could be burning oil, PCV system, etc
