Default Tuning the td04 for a big TMIC

I have an 02 WRX with the following engine modifications.

ERZ up pipe
ERZ down pipe (Heat Wrapped)
ERZ cat back
No cats
K&N drop in air filter
Snorkel delete
Opensource EM running XTP stage Two W/ GM BCS
17.5" LCD HP laptop bought for dataloging and reflashing
GM BCS (controlling my boost 100% better know)
Cobb heat shield

I use ev8siv3's maps for tuning. I think this might be one obstacle I don't know how to deal with. I don't know if I am allowed to post up his data logs here or not. It is his map and I respect the guy so if it is a no no I won't do it. He has road tuned the car so it is not one of his OTS maps if that makes a difference.

The change I would like to do next would be a ebay top mount. I have researched and it seems that this is probably the best bang for the buck mod I could do right now. I would like to know what kind of approach should I take trying to tune for it would be. I would be using a wideband. I am pretty inexperienced when it comes to tuning though. It is a difficult thing to just read about. I only know how to tune once I have done it. Kind of like hands on learning. That is my main goal out of this project would be to gain some tuning knowledge.

Thanks for all the feedback

A bigger TMIC would allow you to run alittle leaner AFR,alittle more boost and more timing advance.
