rutager,
Are you still data-logging? did you have it running without stumbling and now it stumbles, using the same VE table and now you had to triple the values in the VE table? Doesn't sound right, unless something else has changed.

You might want to swap in a new o2 sensor....your current one may be toast and lying to you. I have killed more than a few while tuning, because I tend to drive/log and then I often have the ignition still on, with the engine off..overheating the O2 sensor. That combined with running overly rich etc, while tuning can really shorten their lifespan. Also, if you are very.very rich....the o2 sensor can't read/measure the unburnt fuel and ......it reads lean.

So, i would go back to your last known good tune and install a new o2 sensor....if this gets you back on track, it is an inexpensive fix.....if not, the worst thing that will happed is you end up with a spare o2 sensor
