1) rewrite the calibration to the chip.
2) disconnect battery to reset eec.
3) start car and drive to see if any better.
4) Drive around listening to lil xan

I’m leaning towards it being ignition related rather than fuel as it happens precisely at the same rpm regardless of light throttle or heavy throttle. Seems the only ignition related part I haven’t thrown at it is the coil. Is it possible for a faulty coil to act up this way? I thought they either worked, or they didn’t.

I have it logged (no wideband though). Not sure what I’m looking at/or for. I never got into the nuts and bolts of tuning, and didn’t have the time which is why I paid for remote tuning. Not sure why he isn’t able to take a quick look to lead me in the right direction.
I’m using Tuner Pro RT for logging.

Not sure if it has been covered, but are all the grounds solid?
Does voltage drop at that rpm?
