I have only had my 7 for 2 weeks and I have noticed that it seems to make more power at half throttle than full. Motor and turbo standard and is running some jap 2.5" cat back exhaust. Any advise would be appreciated.

 

could be a clogged cat

 

do a basic check over the whole engines, hoses, clogged cat maybe, or does it not have one, check the play on your turbo and stuff like that

 

Its not Jap its Japanese

 

Sorry if i offended any one with the comment, but i think could be the cat, time for a new exhaust(mmmmm 3").
