IPD - 140796 ECU Power Tune / P3 S60

[PRODUCER]

Hi,
I'm looking for user feed back on the IPD 140796 Power Tune for the P3 S60 T6 platform. Here's my plans, questions and thoughts.
I'm going to purchase it. The EPA standard and MPG will not be effected which is fantastic! I want to replace my turbo inlet and charge plumbing for reliability. I may even upgrade my intercooler. Everything will be Do88 products. I may be installing IPD - 125552 SS Turbo Back Sport Exhaust Kit

question 1; will my MPG be effected by installing better flowing plumbing?
question 2; will my IPD power tune be able to adjust for these changes and will my MPG be effected.
question 3; if I install the IPD exhaust system, will the IPD power tune be able to adjust for these changes and will my MPG be effected.
Below are the links to the parts that I have chosen.
