Well, pull it back and take it apart, since you redid everything it's hart to tell what went wrong. Not exceeding 600PSI of fuel pressure is far from ideal.
P.S.: do you have the check engine light on? If so, what PIDs? Any fuel regulator related codes?

For one single car I think you could get away with the versatuner full. As for the ECU relearning stuff, usually it's mostly throttle and fuel trims stuff. If you get those right from a calibration stand-point these dead times will be significantly less. On my 2.3DISI-T tunes there's hardly any ECU ...

What you feel at low speeds/loads is most likely the fact that with the pops&crackles tunes the fuel is not cut and as an effect the car is sometimes weird to maneuver because it constantly wants to go and not stop. I have my own implementation of pops&cracks which doesn't do that, I posted ...

Most of the parameters in the log are not useful for what we're trying to determine. Also the mPa as the unit for fuel rail pressure offers too low resolution, so use PSI on that one. Also it's the desired pressure not the actual pressure, so doesn't help at all. You do not have engine RPM, load, sp...

If you already have the pump internals don't just keep them in a drawer... install them. As for figuring out what is happening - post those logs you took and fed the AI with them. If you will log again please use this dashboard preset: https://www.dropbox.com/scl/fi/afnzjbrrwsbggjis5w167/Full-Loggin...

Most importantly log those situations that concern you... so an idle log (with the AC off) at least 30 seconds long, some normal driving, coasting, whatever those situations are.

The only things that will improve fuel economy are: - an ECU tune that implements better efficiency, assuming that is possible with the fuel you are currently using; - driving habits. A smaller turbo will not improve fuel economy, will just be a smaller turbo with less top end, because both turbos i...

I would definitely use one of the High Load tunes but not the one for the CP-e CAI because the MAF calibration for that intake is significantly different than what the K&N needs. Probably #3 will be the most suitable in your case but with these modifications you should think about a custom tune....

Post a log and let's see. You may have a vacuum leak or it's simply how your car works.

Maybe you have a stiffer spring in the wastegate actuator... 17-19PSI? This may explain why the WGDC is 0 all this time. As for the timing it's definitely way on the conservative side. But it's hard to tell to run a specific value, you will have to explore that yourself on your car with the type of ...
