Installing Boost Gauge and Turbo Timer

Hi,

I was wondering if anyone on this forum has installed a boost gauge and turbo timer on an Audi S4 yet? I am wondering because I want to know if I should atempt to install them myself or pay a shop to install them. How hard would it be to install a boost gauge and turbo timer by yourself? I am pretty good at reading instructions and following them, but I have never installed them on an Audi before (mainly working on Acuras and Hondas). Please let me know. Thanks.

...take a look at the tech articles on audiworld and judge for yourself :)
