How it works
From idea to tuned car, in a clear no-BS process.
You’ll know what we recommend, why, what it costs, and when it will be ready—before a single wrench turns.
1. Intake & goals
We review your current setup, power goals, budget, and how you use the car (daily, weekend, track).
2. Plan & quote
We outline recommended parts, labor, timelines, and realistic power expectations—no fluff, no surprises.
3. Build, tune, enjoy
We execute the work, tune the car, and walk you through break-in and maintenance to keep it happy at power.
Results
Built to be driven hard.
Cars that leave Beertech don’t just make power—they start, idle, and rip like they should, lap after lap and pull after pull.
"Super fast and professional service at a fair price. Highly recommend!"

"Great shop, great service, fair prices."
Teddy B. — Saint Paul, MN
"I brought my BMW in for a routine oil change, and the service department told me I needed a rear axle seal replacement due to “badly” leaking seals. Wanting a second opinion, I took it to Beertech, where Charlie thoroughly inspected it and confirmed there were absolutely no leaks. I truly appreciate their honesty and professionalism! Beertech is a reliable, reasonably priced, and trustworthy local mechanic that I’ve already recommended to a friend. Thank you, Charlie, for your exceptional service and genuine care!"

Questions before you schedule with us?
Here are answers to what we’re asked most often. If you don’t see your question here, send it in the form below!
Do you only work on BMW and GM vehicles?
BMW and GM platforms are our core focus, but we also work on other high-end performance cars including McLaren and modern Porsche, as well as select other platforms on a case-by-case basis. Use the form to tell us what you drive and your goals.
What kind of power gains should I expect?
It depends on the platform, mods, fuel, and how conservative you want the tune. In your intake we’ll outline a realistic power range based on cars with a similar setup that we’ve already tuned.
Can you help me choose parts before I buy anything?
Yes—and it’s one of the best ways to avoid disappointment. We can recommend a combination of parts that work well together and support your target power without over-spending in the wrong areas.
Do you offer remote or email tuning?
Our priority is local in-house dyno and street tuning, but in some cases we’ll support remote calibration for existing customers or specific platforms. Tell us where you’re located and what you’re working with.
