Default Tuning experience w/Sk2 Tuner Stage 2?

Would like to see if anyone has experience tuning the Skunk2 Tuner Stage 2 cams on a B16 engine , I am currently running a Stage 1 cams with stock valve-train and now I have upgraded to a Stage 2 setup with their corresponding springs, retainers and LMA mods.
Specifically, i would like to see what changes in Ignition are expected to occur, I have already tuned all my fuel tables but I did not touch the Ignition ones, mainly because access to a dyno is really hard to find in this town, but also because I do not have vast experience with them.

When I was running the Stage 1, with its surrounding bolt-ons (header, 2.5" exhaust, sk2 intake, throttle body, CAI. ) and the sweet spot for those were about 1 or 2 deg above stock stockusp30 basemap (s300/Hondata wise)

With these new cams, I did not modify the position of the cam gears, and left them at 0deg default, and backed up my timing changes to the stock map, So now looking for comments, feedback and personal experienced on how much timing you had to add/remove to find the sweet spot on these cams.
Please share your experience if you have tuned those cams before with a relative similar setup.

Thanks !!!

I'm in the same boat. Just ordered some Skunk2 Tuner Stage 2 cams for my B20Vtec.

My experience from tuning my car is you do ignition tuning on the dyno. Add timing until you get max hp and back off 2 degrees.

I am curious what max ignition timing is on these cams.

Indeed, I do know how to tune it, as i explained i was more looking into sharing feedback and experience from ppl who have already done it, and see what they go, but looks like we are pretty much alone :/
Is it strange to see that with soo many Sk2 Stage 2 installed out there is too few feedback/information in general about this.

Here's what I found from someones tune. Looks like they lowered ignition probably due to knock.

Holly [email protected] ... thats about 10deg less of that I am currently using, clearly he's usuing high comp pistons hence the difference, but looks like a lot...

That is stupid low timing. Especially with a big cam. Dumping timing for knock is most likely the case especially if it's a pump gas tune. I waouldnt use that one as much of an example.
