Tuning advice, local shops, prices
 

Hi Guys,

I just recently went back to an AUDI after driving a gas guzzling Grand Cherokee. I am kind of out of tune with the AUDI world and was wondering if someone can steer me in the best direction:

CAR - 2008 A4 Sline 2.0T

Questions:
What chip should i do for a stage 1 tune
Who does the tune locally in Toronto for a fair price
Where should i buy the upgraded diverter valve, and what should i go with
Where is the best place to pick up an intake

Sorry for all the questions, but i figured put it all into one and see if anyone knows since these are probably the most common upgrades.
