Installed the new 85mm throttle body and now at WOT my car boggs down. Normal driving seems fine but with less power. Getting P0050 and P0056 engine codes but the tune was taking care of those I thought. I have a eurocharged tune for the new parts. Did I miss something on the install? I'm going to take another look myself before going to a shop.

I would start by resetting throttle adaptations if you hadn't already. I know whenever we disconnect a throttle we have to reset those adaptations.
