How much power does a remap add?

There is no honest single number. A 2.0 turbo diesel is not a naturally aspirated V6. Torque is what you feel first. Websites that promise “+40 hp on every car” are selling a sticker, not a file written on your dump.

On a stock turbo diesel a careful Stage 1 usually moves the mid-range torque by 40–70 Nm. That is what changes the way the car leaves a roundabout or pulls on a motorway slip road. Peak horsepower on a dyno is a number that depends on fuel, temperature, roller condition and how the car was driven that day. We do not promise a single horsepower figure because the cars in the queue are not identical.

Turbo engines have room in the calibration. Old naturally aspirated engines often do not. A 1.0 EcoBoost and a B58 BMW are different jobs. The file is written on the dump you send, not on a brochure horsepower figure. A Stage 1 for a BMW tuning file service 320d EDC17 is not a Stage 1 for a Volkswagen tuning file service Golf 2.0 TDI even when the catalogue numbers look close.

What the desk actually changes on a Stage 1: boost request and wastegate duty, torque limiters in the middle of the rev range, fuel quantity or injection timing on diesels, and sometimes throttle mapping on petrols. The hard limits that protect the turbo and the gearbox stay. Peak power is secondary. Mid-range torque is what the driver notices.

Stage 2 is different. It assumes the car already breathes better — usually a freer intake and a downpipe. The numbers move further because the hardware can support them. Flashing Stage 2 on stock exhaust is how you get knock, a limp, or a car that feels no stronger than Stage 1 and smells like a problem. Write the hardware list on the ticket.

On our menu Stage 1 is priced by year band (60 / 70 / 80 €). Stage 2 is 100 €. 1 credit = 1 €. You are paying for a file written on your dump, not for a generic pack that claims the same gain on every car. Targets can be noted on the ticket, but they are not threats. The engineer writes to the hardware and the read.

Brand pages list the marques we write for. Volkswagen tuning file service, BMW tuning file service, Ford tuning file service, Renault tuning file service and the rest behave differently. The file still follows the dump you send. A restricted Drive link or a 200 kb snippet turns a same-day Stage 1 into Thursday.

Circuit and motorsport use only. We do not homologate cars for the public road. The workshop briefs the end driver. Local law stays with you.

Common mistakes: chasing a dyno number the ticket never asked for, ordering Stage 1 on a car that already has a downpipe, or treating every turbo diesel as if it will gain the same torque. The honest answer is mid-range torque on a healthy stock car, written from the dump, not a single horsepower sticker.

Frequently asked questions. How much power does a Stage 1 add? There is no honest single number. Mid-range torque of 40–70 Nm on a stock turbo diesel is typical. Peak horsepower depends on the car, the fuel and the day. Why not promise +40 hp? Because a 1.0 EcoBoost and a B58 are not the same job, and the file is written on your dump, not on a brochure. Does Stage 2 add more? Yes, when the hardware already breathes better. Flash Stage 2 on stock exhaust and you get a limp, not extra power. Is this for the public road? No. Every file is for closed-circuit, private track, off-road and motorsport use only.
