Well, based on your first log...your WOT pull...
your car is obviously running lean...if you dont have a wideband you want the narrowband to at least read 0.88-0.94 (.88 being on the lean side, .94 pbeing on the rich side, so you want to be in the middle of that range)
You will need lot more fuel at Wot...My guess would be 10-15% more fuel at least...
you get that much timing and knock at the same time when your car is extra lean, that the computer dont know what ot do with itself. Depeding on your boost 18-22 degrees of timing is ok.... but just not on the tune you have...
But you realy want to be around 18-20 degrees on pump gas and on less than 25psi. Any more boost you will need to pull more timing. only way to pull timing in your setup is to add fuel.
Now for the goofy sh!t you should fix....
You have 660cc injectors, a key diver chip probably set for 450cc, and vpc with a 550 chip. This is the most ridiculous thing I have ever seen. All these things conlit each other and you will never get a clean cruise, mybe a clean wot, but probably not the best...
with your turbo you problably should at least go with 1150cc jsut to have the extra room to grow with your setup.
but if you are not willing to upgrade injectors, you should at the very least do this...
Get a keydiver chip for your 660cc injectors, and get a 450cc chip for your vpc. Doing this might help with your cold start and poor idle, as long as your fiav and isc are good. also, you have to make sure you set teh gain knob properly on your vpc, ths is what most people have troubles with and messes up their idle.
you always...i mean always get the ecu chiped to compensate for the injectors, this way you dont have to fight conflicting piggy backs, and you can jsut set the piggybacks to zero. So you can start with a good baseline.
with that said..I dont have time to help you with your cruising tune.
Hope this helps. Just dont blow teh damn thing up, Harry spent a lot of time on it.
Disclaimer: this is all generalzed information, use it best you can..
Also, all things being equal, I am assuming you know what you are doing, and you have no boost leaks, all sensors are with in spec, and everythign lse is good...
Make Sure Base timig is set to 5, and AFPR is set to 37.5.
