It looks like a graph from a 3582 1.06 sized turbo without avcs. And it looks like octane is in order for your build .
I will go check system leaking this weekend to make sure everything is well sealed. its a little bit leaking from turbo hotside to downpipe v band flange but its sorted now and i know that wont affect spool up.

I did have avc-s and it helps a lot during spool up. but im suspecting 2.1L with .82 gtx3076, it will be slow spool up, is that correct? or might be i have too long up pipe, will that affect spool up? or i have too much timing during the spool up?

Thanks anyway matey!
