Hi everyone! I'm new to this Audi forum and i wanted to ask a few questions!

-First off i have a 2.0t b7 '08 and I've been thinking of a couple mods i want to accomplish

-APR tune stage 1, I've found a reputable dealer whom already has the equipment for the tune for about 670$ he was nice enough to inform me that APR sometimes offers deals for 4 tun programs at the price of one.

-How often does APR offer this discount for the A4??


-Next, i have the titanium rim package but prefer a different style. If you could i would like you to post a picture of either your favorite rims for our cars or your own. On a side note i want to eventually lower the car out and have the wheels flush with the wheel wells. ( so what general offset do i need, whats the fattest tires i can get, etc)


-Also next, i know it sounds kind of tunerish, but i would like to know more about the enclosed turbo system and how to allow external pressure blow off (im new to turbos so bare with me, im also a former big block man XD )
(something called a divergent spacer or something is what ive been reading about)

-finally, how difficult is it to both lower the A4 and instal a boost gauge (please list some good manufacturers/internet sites for Audi you trust)

Thanks guys
