The end result is the same, if not better when done on the road with the correct equipment as its being used in real life situations with correct airflow and temps etc..

In that case i would rather pay the correct amount for what the job is worth compared to X tuner who charges £££'s more because of their expensive toys that they need to pay for. Even when done on the rolling road when taken out on real road the setup done by the tuner may not be what the car needs to be able to put the power down or may not be how the customer wants etc etc..

For this reason when done on the road with the customer in the car either driving or holding on to the equipment like laptop and gauges or meters etc. You get much better feedback for the changes that have been made part throttle, on and off boost, driving hard through gears, comming to a standstill from high revs, idle etc etc... These things are hard to get right when on the rollers without the right airflow and drag friction etc etc..

IMO a rolling road is great for being able to do long jobs quicker and also diagnois problems quicker when compared to the next tuner without a rolling road for obvious reasons. If you need to adjust anything when out on the road you need to go back to HQ each time, when on the rollers you just get out and do what needs to be done probly quicker than the wheels stop spinning on the rollers.


Lots of my past cars have been on rollers and obviously setup on the road too..
When compared i will always choose the real road tune over the rollers.

This is only my thoughts after having spent ££££'s on tuning over the years to find out the hard way.
