MED9 2.0T with compression ratio change

[uprev]

Hey all, I am tuning a 2009 A4 with 2.0t that has had forged pistons installed and compression ratio upped to 9.0:1

With this will naturally come more torque per RPM, so would it be best practice to scale the Optimum Torque tables accordingly? Or is there another preferred method?

Thank you in advance!

Likley the standard tuning process will be good enough if you?re running good fuel (93oct/98ron) where you will see the biggest change is WOT and higher boost areas that will be more susceptible to detonation/knock given the new higher compression ratio
