Default Critique my tune

Afternoon, I was hoping to get some insight on my VE table. 02 mk2 DIY turbo kit. Stock bottom end stock 5spd running rx8 blue (550cc) injectors they weren't pulled from a stock rx8 so they very much could be fakes. I did have someone put them on a cleaner and test the spray pattern and all were within so much of each other so I decided to run them 2 years ago. My current biggest issue is heat soak and running pig rich through my ve table.

When is it running rich? What conditions? Do you have a log?

You don't have DFCO enabled which would probably help a bit. You have really high values in the VE table in decel conditions and you're not cutting fuel right now, which is what DFCO will do.

Heat soak after parking the car for a minute? I had to do a ton of afterstart enrichment to combat that when I was running a speeduino. My old settings are here https://tunes.speeduino.com/#/t/8y13...tartupIdle/ASE
It would probably be better to run closed loop fuel and have that help at idle, but turning up the ASE worked well enough.

So my tune isnt fully complete. I had someone who's known on FB [won't say the name he went through a roast erra] but the tune was never completed over 5k rpm. But I had moved to closed loop and it was great. Everything stayed within range. I had since then moved to openloop because I know that your tune has to be dialed in before switching to closedloop and mine isnt. I can't get a log right now as my cars on ramps due to me fixing a leak under my manifold (taco taco mani) where the wastegate bracket that I made was leaking. The fitting im using off of the wastegate is unique and you can't find them anymore from ebay.
