Cobb 3 Port question
 

Since I didnt see a Ralliart Tuning section, I posted here in hopes of some answers. I'm in the middle of an Evo x turbo swap, and one of the parts I'm installing is a 3 port. I may end up having it tuned locally by Cobb so thats the reason for the Cobb 3 port.
What needs to be changed in the rom ? I know this is a vague question, but for example the grimspeed 3 port i believe the WGDC table needs to be dropped 30% to avoid overboost. can some one tell me if Cobb ECBS is similar or what I need to do just as a starting point.
I am new to tuning and intend on learning this for my self. I am just looking for some answers not to be told to go to a pro. This is becoming more than just a Hobby for me, and I do much more technical things for a day job, so I'm not intimidated, I just need data. Thanks for your help. One last thing I did search and search and read countless threads. None of them had anything about the Cobb specfically. I am aware that cobb has a map for this, but I want to know whats in it. Can I look at that map with evoscan/ ecu flash ? I have the tactrix and all software already. Again, thanks for the help in advance.
