Default PCLINK G4. 2.1L stroker tune looking for some help/advice

Hey guys just built a 2.1 L stroker build and i am looking for anyone who has this setup or that has experience tuning this type of setup.

I have gtx3582 with je ultra series pistons. closed deck ej20 with arp 625+ head bolts and manley h tuff rods with 625+ bolts on those as well. stock ej25 crank.
Heads have been ported and polished by me.

I have tuned this car before but since this is a stroker build now i'm outside of my comfort zone. I would like some input from other with experience.

Here is a screenshot of my current ignition table. Let me know what you think.

what heads are you running, it looks pretty conservative to me, but if you feel a little sketchy, take a degree out and run it

HLA version 1 heads. They are ported and polished. I just bought new fuel rail and 1200cc injectors along with tuner nerd det cans. This should help for sure. Thanks for the reply man. What kind of timing up top are you used to seeing?Here is what I am running now. I am spraying meth with this setup. Just waiting on the fuel rails and injectors to turn up the boost. Running 23 psi right now.

I think your afrs look pretty aggressive and lots of timing but you have a meth system. just make sure you dont run out. Right now i am running only like 12 or 15 degrees at the top. but I am on a 91 tune so yeah pretty maxed out. what is HLA BTW?

I am not pulling gas with the meth. I am basically only using it for cooling. My afr target is like 11.5 at the top the meth is dropping it down to 11. If I do run out it's not i deal but i shouldn't be leaning out enough to do any damage unless my timing is crazy i guess. HLA means hydraulic lash adjusters version 1/2 heads I think. I am running 94 octane fuel (petro can). I will keep the aggressive timing in mind when turning up the boost. I will likely back off some for sure before turning it up. I am still waiting for the det cans. Right now the car feels pretty good with the current timing I am going to tweak this a little and see how it goes.

Why do you think my afr is aggressive btw isn't 11.5 full safe? What do subbie guys run?

I am used to tuning direct injection setups.
