I'm just an armchair tuner wannabe but its not what I thought it might be in terms of how it was tuned. I still think its tune related though. No doubt the throttle closing is what you feel, as to why it does that when you ease into the gas in third I am not sure but it doesn't do it on a WOT run. You also have no knock on your WOT run, negative or positive which is surprising, but you do have knock in that part throttle log. I also don't see rail pressure in any of your logs, are you using a different config when logging for your tune revisions? Not sure how anyone is keeping and eye on your fuel pressure with these logs.
