Default t6 help

before i purchased my 99 s80 t6 i test drove quite a few others and i remember the cars having quite a bit more pull than mine does.. sometimes it feels like it should and like the other cars but other times when i get on it she doesnt feel so powerful. is there anything i can check in the turbo system? does the turbo tend to wear out over a certain amount of miles? mine has 120000. all logs have been kept and all servicing has been done by a certified volvo dealership. its currently scheduled to go in for the 120000 mile servicing next week ($400 if theres nothing wrong with it) im a car guy and can build an engine or a tranny no probbut im not to keen on these volvos and dont realy want to mess with it too much besides looking at stuff. should i have then check the turbo system while its in the shop? will they check that anyway? the car shows no codes or messages and purrs like a kitten and the turbo does work and it works every time its just that sometimes it doesnt feel like its as powerfull as others.. for instance and i dont burn out all the time im a family guy and stuff but i do get on it sometimes and i noticed that from a stand still sometimes it will burn tire and sometimes it feels like a dog. i know the turbos are working cause there is lag and then it pulls hard but after it shifts to seccond its like all power goes away.. the other cars i drove had a smooth power curve all the way through this one drops off after the shift. is it possible only one side is working? its twin charged obviously but i dont know if that means theres two separate sides to the system. any help apreciated!!!! and where the heck can i get an auto dimming replacement mirror and a bass/teble and fader ****!!! OH i almost forgot.... its not because i have the STC on.. if i turn stc off and i stomp on it at a stand still it willNOT burn tire at all... after about 100 feet you can feel the turbos start kicking in and it starts pulling a little harder. could i have something in the system blocking air?

The boost control valve might be going bad.

The mirror you can only get from Dealer because it is a control module and they need to download software to make it work.

The ***** try the Dealer as well.

It is pretty expensive. Volvo thinks those valves are GOLD!!
See what the shop says.

Do you also get like a hesitation while driving at highway speeds while driving at a steady speed?

Have the shop also check for codes there might be some but no check engine light.

Yours is a 1999 so you can't access the onboard to see what systems have codes.

I would say about $100.00 to $200.00 for the valve.
All depends on the market.(I know they say all parts are the same at all dealers but I know better.)
