Garage Whifbitz

Garage Whifbitz is a performance-focused workshop and dyno centre in Caldicot, known for ECU remaps, rolling-road tuning and a parts/e‑commerce arm. The team services a wide range of petrol and diesel performance cars and offers in‑house diagnostics.

Visits are by appointment only; the site lists weekday opening hours and a contact phone and email for bookings and parts enquiries. Social channels and directories show recent project work and customer feedback for reference.

A focused performance workshop with a rolling road and tuning expertise. Expect hands‑on diagnostic work, dyno sessions and parts fitting rather than a showroom experience.

Look out for:

• Rolling-road (dyno) tuning and performance remaps.

• ECU and software optimisation for petrol and diesel engines.

• Parts sales and fitment from the site’s ecommerce offering.

• Workshop diagnostics, fault-finding and bespoke builds.

Best way to experience it:

Call or email ahead to book a dyno session or consultation, bring full vehicle details and any fault codes, and allow time for diagnostic work and follow-up tuning adjustments.

• Visits are by appointment only; contact before arriving.

• Weekday operation; closed at weekends per listings.

• Bring vehicle paperwork and a clear description of issues or goals.

• Phone and email listed on the official site for bookings and parts enquiries.
