A Dyno Sheet for a Remap: What the Customer Should Get After the Tune

A dyno sheet for a remap is the one thing a customer can hold after the job. The tuned file itself is invisible: they cannot open it, read it or show it to anyone. What they can show a friend, a forum or the next owner of the car is a page with their car’s name on it, a curve that goes up, and your logo in the corner. This article is about what that page should contain, how to publish it without handing a customer a mistake, and the tuning certificate that goes with it.

What a customer should get after a tune

Two documents do most of the work. The first is a dyno sheet: power and torque, stock against tuned, drawn over the rev range. The second is a tuning certificate: one page with the car, its registration, the changes applied and the gains, in your brand. Neither replaces the other. The dyno sheet is the picture people share; the certificate is the record that says what was done to this car and by whom.

In TunerSuite both come from the request itself, so the vehicle, the registration and the work ordered are already there. Dyno Studio handles the sheet; the certificate is offered on every completed request.

A dyno sheet without a dyno

Most file services do not have a rolling road, and not every car is measured. A dyno sheet can still be honest if it is drawn from real data rather than invented. When the vehicle catalogue holds the engine’s curve shape, the chart follows that shape, scaled to the stock and tuned figures; VIN, operator and stage are filled in from the request. A car that is not in the catalogue yet can be entered by hand — make, model, stock and tuned power and torque — with every point editable afterwards.

Two safeguards keep the sheet believable. Atmospheric corrections are applied, and realistic-gain guardrails flag a gain that does not make sense for the engine before it reaches a customer. A sheet that promises more than the car delivers does more harm than no sheet at all.

When you do have a measured run for a vehicle, the Vehicle Hub plots your measured curves with a “Measured dyno” badge instead of the illustrative one, so customers looking at that car see real results from your own work.

Publish it, and take it back if it is wrong

A dyno sheet should never reach a customer half-finished. In Dyno Studio a dyno starts as a draft that only your team sees. Publishing it tells the customer on the channels you use — email, Telegram, push — and puts an interactive chart on their file page, with a PDF export that carries your own dyno logo on a full or a simple template, with your disclaimer. If something was wrong, revoke it and republish once it is right.

In a dealer network, a dyno you publish for a job that came from a dealer appears on the dealer’s portal too, so their customer sees the same chart. A dealer’s own staff can create and edit dynos on the requests they sent you.

The tuning certificate

Every completed request offers a one-page certificate the customer downloads beside the tuned file: your logo and brand name, the vehicle’s registration, the changes applied and the estimated gains. It comes in a dark premium design by default, and the same certificate is attached to the delivery email, so the customer has it even if they never log in again.

Before a job even exists, the Vehicle Hub can produce a performance certificate for a chosen stage next to the quote, clearly labelled as projected figures. It is a useful thing to send a customer who is still deciding, as long as it says plainly what it is. And with the optional Dealer Pro plan, a user’s own logo and contact details can appear on their certificate, quote and dyno sheet, so a dealer can hand branded documents straight to their own customers.

Close the loop with a rating

Once a tuned file is delivered, the customer can score the job from 1 to 5 and leave a comment from their file page. Your team sees it on the request, and the “file ready” email invites it. It is the simplest way to find out which jobs went well and which customer needs a call.

What to put on the sheet, and what to leave off

A good dyno sheet is plain. It shows stock and tuned power and torque over the rev range, the car and its registration, the date, and your brand. It says clearly whether the figures were measured on a rolling road or drawn from the engine’s known curve, and your disclaimer covers the rest. What it leaves off is anything you would not defend if the customer took the car to another rolling road next week: a peak figure the guardrails flagged, a curve drawn for a different engine, or a projected figure presented as a measured one. The customer will share the sheet. Make it one you are happy to see shared.

What it costs

Dyno Studio and the tuning certificate are part of the TunerSuite portal: a £699 setup, then £49.99 only in a month you deliver ten files or more. The pricing page has the full breakdown. You can see a published dyno and a certificate on the live demo, and the Dyno Studio page lists everything above in one place.
