I understand where you're coming from but I think the main issue with people saying "just change this or that" is that they don't want to give advice over the internet which may damage all of that hard work you've put into your pride and joy.
Very difficult to tune a vehicle you can't see.
Post a couple of decent logs (like an hour long) and then people may be able to have a better idea of how to help you out.
Best thing s to go through the AutoVE tutorial and follow the procedure...then do a RAFIG/RAFPN and that's be a pretty good start.
One other thing is...alot of the guys on here do this for a living...so you're getting advice you'd normally have to pay for.
If you just want the vehicle tuned and running well.....try someone like 'Blackbear performance'.
