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
Erik

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