Question 1

Is remapping safe for my engine?

Accepted Answer

Yes. We tune within the engine's safe operating tolerances using custom files written for your exact vehicle, not generic off-the-shelf maps. Manufacturers leave significant safety headroom to cover all markets, fuel qualities, and service intervals — we work within it.

Question 2

Will a remap void my warranty?

Accepted Answer

A remap is detectable and may affect your manufacturer warranty on powertrain components. We offer a tuning warranty on the work we carry out, and the map can be reverted to stock at any time if you need a dealer visit.

Question 3

How long does a remap take?

Accepted Answer

Most cars are done in 45-90 minutes. We read your ECU, write the custom file, flash it back, and road-test before you collect.

Question 4

Do you come to me?

Accepted Answer

Yes — we cover Ely, Soham, Littleport, Witchford, Haddenham, Stretham and the surrounding Cambridgeshire villages with a mobile service. Workshop appointments also available.

Question 5

What gains will I actually see?

Accepted Answer

Stage 1 turbo petrol/diesel typically gains 25-40% on both BHP and torque. We'll give you a realistic, vehicle-specific estimate before you book.

Question 6

Can you remove DPF/EGR/AdBlue?

Accepted Answer

Yes — for off-road, motorsport, or export use only. We'll discuss legal use cases when you enquire.

Question 7

Will a remap affect my insurance?

Accepted Answer

You must declare a remap to your insurer. Most modern insurers cover modified vehicles — we'll provide documentation of the work for your policy.

Question 8

Will a remap improve my MPG?

Accepted Answer

Usually yes — by 5-15% if you drive sensibly. Stronger low-end torque means you can sit in higher gears at lower revs. Drive it hard and you'll use the extra power instead.

Question 9

Do you tune petrol and diesel?

Accepted Answer

Both. Turbo petrols (TFSI, TSI, EcoBoost, N54, etc.) and modern common-rail diesels see the biggest gains. Naturally aspirated cars see smaller but still worthwhile improvements.

Question 10

Can I revert to the stock map?

Accepted Answer

Yes. We always back up your original file before flashing. A return-to-stock takes 30 minutes and is included for life.

Question 11

Do you remap vans and commercial vehicles?

Accepted Answer

Yes — Transits, Sprinters, Vivaros, Tippers, and pickups (Hilux, Ranger, L200, Amarok). Economy and torque-focused maps are popular with fleet operators.

Question 12

Where are you based in Ely?

Accepted Answer

We're an Ely-based ECU remapping specialist covering the whole CB6 and CB7 area. Workshop appointments by booking, and a fully mobile service across Ely, Soham, Littleport, Witchford, Haddenham, Stretham and the surrounding Fenland villages.

Question 13

Do you cover Soham, Littleport and Newmarket?

Accepted Answer

Yes — Soham (CB7), Littleport (CB6), Newmarket (CB8), plus Sutton, Wilburton, Wicken, Burwell, Fordham, Isleham, Haddenham, Chatteris, March, Downham Market, Waterbeach, Cottenham and Cambridge. Mobile remapping at your home or work, no extra charge.

Question 14

How much does a Stage 1 remap cost in Ely?

Accepted Answer

Stage 1 maps in Ely start from £249 fully fitted, including a stock-file backup and our lifetime tuning warranty. Stage 2 from £349, DPF/EGR/AdBlue solutions from £199. Vans, pickups and 4x4s from £279.

Question 15

Can you remap diesel vans for Ely tradesmen?

Accepted Answer

Yes. Transit, Sprinter, Vivaro, Crafter, Boxer and Ducato are all bread-and-butter for us. A torque-and-economy remap typically returns 10-15% better MPG on motorway runs and noticeably stronger pulling power loaded — ideal for trade vans working out of Ely and across the Fens.

Question 16

Do you remap modern cars in CB6 and CB7?

Accepted Answer

Every car under about 18 years old has an ECU we can read and rewrite — from a 1.0 EcoBoost Fiesta to a B58 BMW M340i. We support OBD and bench/boot flashing for all common ECU types found on cars driven around Ely.

Question 17

How quickly can you fit me in?

Accepted Answer

Most Ely customers are booked in within 2–5 days, often same-week. Mobile slots tend to be at short notice — give us a call or drop your reg in the form and we'll come back within the hour.
