This weekend I tried to adjust the wastegate preload. the preload was far too stiff. Maybe 6 full turns. I adjusted it to 3 full turns and took it for a road test. It seems that it had slightly better spool but nowhere near from what is supposed to spool. Probably the hotside must have cracks. Here's the new log

Having to much preload on your wastegate isn't a bad thing, it would actually help the spool. You have other problems going on. I have that spool on a turbo the size of a black on my 2.4 so you have a leak somewhere.
Another probable cause which is likely to be the problem. When I decided to replace the wastegate, I ordered a Forge IWG for evo 9, as i own an EVO 9 MR. When I tried to install it, i noticed that it was not a direct fit to the hotside door. I googled the turbo part number, just to find out that it was a turbo from EVO8 MR. I do not know if it has anything to do with this, but probably the door stays open. Forge, Turbosmart and other companies that offer actuators, they offer actuators for evo4-8, and different for evo 9. Anyhow, the turbo, manifold and also the wastegate will be replaced soon but I before I switch turbos I want to find where this boost delay comes from
The wastegate difference is due to the bigger compressor housing on the evo9 turbo's. Hotsides are identical in external sizing and wgate arm placement.

Sooo how are guys doin? As I am patiently waiting for my parts to arrive, I decided to share some pictures of my build
4G64 Block. It was actually in a very good condition. I even avoided to bore it, which was preferred for obvious reasons (Thin cylinder walls, HG issues etc)

Suprised that you are going that all out and big turbo, but h beams
I think the Carrillo Pro H is a good choice for the 100mm crank. It will reduce rotational energy to reduce chance of crank fracturing at #4 oil port. I'm not a fan of LR because I like the pistpn rings spread out as far as possible to reduce cylinder wall wear.
You got a lot of nice stuff on this build congrats. But I think you made one mistake. I can understand wall thickness of the block, but how do you know the cylinders are true? Hate to see you spend all that cash and have oblong cylinders in the block, specially when it came to a used 64 block. I was kind of surprised you went H beam rods as others did, but I know Carrillo makes nice stuff and those should be fine. Only other thing I can say is wasted money on those race balance shafts personally, and I think you should have went with a larger runner intake mani to help the air get into the engine given the larger displacement. Other then that thing should be a monster nice job. Looking forward to some #s.
