What are the terms of using the dyno?

  • Dyno power run (up to 3 runs) is charged at £90+vat
  • All dyno time is chargeable at £90+vat/hour
  • Although we take as many precautions and check as much as we can, all dyno runs/usage are at the customers own risk.
  • To reduce time on dyno please make sure of the following:
    • The car is in good health ready to be tuned/tested. It has been serviced according to manufacture specifications.
    • All Fluid levels are checked. Any coolant/oil/fluid spillage into the dyno will have a 2 hour labour charge added in order for us to dismantle and clean the dyno. Additionally you will be charge for extra time spent on the car to remove fix, and start mapping again.
    • Any damage caused to the dyno by tyre failures or fluid leaks will be chargeable
    • No Tyres are to have puncture repairs
    • Tyres are at usual operating pressures
    • No winter tyres fitted to the car (these get hot and melt)
    • No treaded track tyres (these get hot and melt, and exceed noise limits)
    • The car has to be aligned correctly with no extreme camber. A misaligned car can give erroneous results
    • Any work carried out while on the dyno will be charged at £90+vat/hour
    • No exhaust leaks as these will affect mixture readings from the exhaust
    • You should advise the operator of the rev limiter and if one is on the car
    • All towing eyes must be accessible in order to safely strap down the car. If not accessible our priority is to secure the vehicle safely so cannot accept for damage to undertrays, exhausts etc
    • Cars should have at least 150mm clearance under the car to clear the Rolling Road. Any adjustment or removal of parts will be charged at £90+vat/hour

Can I watch the dyno?

  • Due to Health and Safety you should not be in the workshop but you are welcome to watch from the dyno roller shutter door. If a car is particularly noisy it may be necessary to lower the roller shutter

I have been tuned by another company, can you do a power run?

  • We would rather not get involved in measuring tunes from other suppliers but  we can provide you accept it is entirely at your own risk. A poorly tuned car can have a catastrophic failure when pushed on the dyno.
  • We would advise that a Health check is performed and diagnostics are connected when we do this so we can make sure everything is safe.

What does the dyno measure?

  • It measures the torque applied to the wheels on a wide open throttle run. From this, power is calculated to give you a power and torque curve. This can be shown at the wheels or the calculated at the flywheel numbers. The dyno measures the rundown losses and adds this measurement to the measured power at the wheels.


Please fill out our "Tuning Form" before any tuning or modification work is carried out. The forms are available in the reception.

All cars that are remapped/tuned modified should be declared in full to your insurance company.

If any of your prerequisites that you make on the tuning form tuning cannot be fulfilled we will refuse to work on your car.

We do not map cars to give you a set power, the car will be tuned to what is safe for the car
Any non-advertised modification to cars will not be given a completion date or defined by a leadtime.

For reliability regular Health Checks performed by MRC Tuning should be taken out.
Even though we check every car getting more power will reduce the life of wear and tear components.

The most reliable modifications to a turbo car will be to get the best exhaust and intake on the car to reduce stresses, with the remap.

Modifying cars in the UK generally do not add value to your car and you should be aware that in most cases will devalue the resale value of your car.

When you go to extreme modifications > 50% gains, you will have to be prepared for parts to break and severely shorten the life of engine and drivetrain components. While we tune the cars to be safe, lifetime of parts will be shortened.

Any modification that is not "off the shelf" or a common upgrade will encounter more risk of failure.

Any lowering of compression, will mean less mpg and less driveability off boost. It can also cause the idle to be uneven.

Any non OE camshafts can cause a rough idle.

Modifying a normally aspirated car to be charged is not going to keep OE safety protocols in the ECU for boost levels.

Any car that does not have egt and wideband measurements in the ECU should have external gauges fitted to check the car is safe at all times.
