I finally got around to taking my '11 S5 Cab to PAC GERM after a reco from a relative. For starters, Tyler and Shawn have answered every email with the many questions I had since I'm new to the whole tuning/mod thing. Prompt and detailed replies. I haven't gotten this from other shops. I'm still waiting for two months for a return of a phone call/email from one place. With PAC GERM I feel I am getting super knowledgeable and prompt service and all my questions/options answered in detail with price quotes within a day! I think you'd be hard pressed to find that kind of rapid response from a lot of places. And to top it off, a super high end shop, great work and solid customer service. They know their shite suffice to say. No nonsense attitude. That's what I'm looking for in a shop. Did the REVO Stage 1 and now will be going back for next phase of pulley, stage 2, etc. I'd give 'em a shot.
