How it works

We verify the complaint, scan every module and follow the factory test plan to find the actual cause.

02

Estimate

Findings, photos and a written estimate. Nothing is done without your approval.

03

Repair to spec

Correct parts, torque specs, fluids and coding, plus any software the repair needs.

04

Road test

We verify the fix and walk you through exactly what we found.

Quick question?

Request a call back

Leave your number and we'll call you back during shop hours. Add your VIN and we can look up your car before we call.

Build your car

Tell us the goal.
We'll plan the build.

Pick your car, set the power you want and how you'll use it. The build planner lists every part and supporting mod it takes, for street, track or full competition builds.

Builds done right, not cheap. Every build starts with a health check and a written plan that covers fueling, cooling and drivetrain, not just the parts that make power. If you're after the cheapest way to more boost, we're not the right shop.

FAQ

Common questions

What warranty do you offer?

Repairs are covered by our parts and labor warranty when we supply the parts. Ask us for the full terms with your estimate.

Can I bring my own parts?

Yes, we'll install parts you supply. Our warranty covers parts we source and the labor to install them, so customer-supplied parts aren't covered, and neither is the labor to diagnose or replace them if they fail or turn out to be the wrong part.

Do you offer financing?

Yes. We offer flexible financing for repairs and performance builds. Ask when you get your estimate and we'll walk you through the terms.

Do I have to go to the dealer to keep my BMW, Audi, VW or Mercedes warranty?

No. Federal law (the Magnuson-Moss Warranty Act) lets you have maintenance done at any qualified shop without voiding your factory warranty, as long as the work follows the manufacturer's schedule with correct-spec parts and fluids. We document every service on your repair order so you have the record.

What diagnostic equipment do you use?

For BMW and MINI we run ISTA, the same factory software BMW dealers use for fault-finding, test plans, coding and programming. For other European makes we use professional multi-brand diagnostic tools, and we follow the manufacturer's test procedures rather than guessing from a code.

Do you use OEM parts?

Yes. We source genuine and OE-supplier parts (the companies that build the factory parts, like Bosch, Lemförder, Mahle and ZF) through European parts distributors and BMW dealer wholesale. If an aftermarket upgrade is the better choice for your goals, we'll explain why and price both.

How do your prices compare to the dealer?

Our estimates are built from published labor times and real parts pricing, and you approve a written estimate before work starts. Most owners save meaningfully versus dealer service, without giving up factory-level diagnostics or parts quality.

Can you help me modify my car?

We plan and install performance hardware: intakes, downpipes, intercoolers, fueling, turbos and drivetrain upgrades. We don't do software tuning in-house; that's handled by independent tuning specialists. Start with the Build Your Car tool to see what your goal takes, then we'll confirm the plan after inspecting the car.
