Performance upgrades in River Falls and Hudson
Turbo, exhaust, suspension, brakes, and ECU work for European, exotic, and seriously built daily drivers.

When you need this work
- The car feels soft or overheats under load after a bolt-on
- A check engine light after a turbo or exhaust install
- You want dealer-grade work on a non-stock European car
Work on this bench
BMW jobs lead this page because that is the work the shop wants seen first.

Why this shop, not the Crest View cluster
Hudson Auto Center, Tire Pros, and the dealer row on Crest View Drive win on volume. The Upgrade Shop wins on mixed work: a daily-driver repair and a turbo or rebuild in the same building, with Peyton Sherman on the job instead of a rotating writer.
Competitors in this market rarely publish price ranges, warranties, or real work photos. We will tell you the range, the downtime, and whether the car is safe to drive home. If it is not, we say that first.
Questions about performance upgrades
Can TUS Shop Inc. upgrade a modified European or exotic car?
Yes. The Upgrade Shop builds performance work around the car you actually drive, including turbo, exhaust, suspension, and ECU calibration on European and high-end platforms.
Do performance upgrades void a factory warranty?
Factory coverage varies by maker and by the part being changed. We tell you what the install touches before a wrench turns, and we document the work.
How long does a typical performance upgrade take?
A focused bolt-on or exhaust job is often same day or next day. Turbo, fuel, and calibration packages are scheduled by parts lead time.
Do you tune after the hardware is on?
Yes. Hardware without calibration is unfinished. We plan supporting mods and ECU work as one job, not as an afterthought.
