Engine Tuning & Remapping

Welcome to Fourth Avenue Tuning!

If you’re looking for expert levels of engine tuning and remapping in the Somerset and Avon areas, then Fourth Avenue Tuning are the professionals to call.

In response to customer demand, we’ve combined our several combined decades experience in the auto services industry to create a tuning company able to provide remapping, tuning, diagnostic and related services to a wide range of trucks, tractors and general vehicles.

We can offer the latest in non-intrusive remapping and tuning to most makes of trucks, tractors, cars, vans and other vehicles using state-of-the-art tuning equipment either from our base in Midsomer Norton or at your home or business premises.

Vehicle tuning - remapping and tuning isn’t restricted to high performance cars; just about all cars, vans and other vehicles will benefit in terms of improved fuel economy and performance with an Fourth Avenue Tuning remap.

Truck tuning - you could save considerably on running costs with an ECU remap as you’ll almost certainly gain in fuel economy with improvements of 10% possible - imagine the difference that would make to your annual fuel bills.

Tractor tuning - remapping will give your tractors more power and torque with improved fuel efficiency so saving time and money. More power means your tractors can handle increased workloads and complete certain tasks in less time, so you’ll save on operational costs through improved fuel economy and possibly reduced man hours.

DPF and EGR services - emissions control equipment fitted to modern diesel engines such as the DPF (Diesel Particulate Filter) and the EGR (Exhaust Gas Recirculation) can cause issues so we offer services to combat clogged DPFs and malfunctioning EGR valves.

Diagnostics - why pay main dealer rates when we use similar diagnostic equipment to isolate and diagnose faults.

We use cutting edge modern remapping, tuning and diagnostic equipment such as Dimsport Genius, CMD Flash, Alientech Kess and K-TAG amongst others. With all remaps, we make a copy of your vehicle’s factory ECU settings and store it securely so it’s available if you should wish to return to default settings.

Payment is swift and easy as we take most debit and credit cards (except American Express).

We’d be delighted to advise on how our remapping and related services could help you get more out of your truck, tractor, car or other vehicle so have a look round our website for further information and get in touch today.

We look forward to helping you.
