Thanks for the response, I appreciate it.

Motor = completely stock
Correction factor = 1.0
Finally got back home and here's the plot:

I really like the ATP cutout, and will look into the EVO exhaust. My tuner was against spending on an EWG at this point since that acts upstream of the turbo and wouldn't help my exhaust flow issues - which made sense to me at the time, do you disagree?

Regarding the carbon cleaning - is this just general Seafoaming? About how often (miles) do you reccommend something like this for the 2.0L?

Again, thanks for the help/advice,

Did they put a fan ontop of the TMIC?

The Pdrive is killing the top end. You gotta ditch it. Get a Greddy EVO exhaust. Its not loud at all and its 3 inch. Otherwise, A cutout will help. I used the ATP boost actuated one several times and made 10 to 20 whp depending on the exhaust the car had.

EXgate would solve all the issues with the prodrive exhaust. However, Its loud as hell when on boost. So that is up to you. Typical gains are 10 to 20whp with an external gate.

Also.. You did not mention if this was a stock motor and how many miles on it. You might need to carbon clean it. These 2.0s really carbon up bad. After the cleaning they tend to take full timing. Plugs should be new NGK one step colder and gapped to 026.
