From figures I’ve seen over the last five years the GTI’s often put out a bit more than the stated power yet the R’s seem to come in around the published figures on the more respected rolling roads.
It’s no use looking at the graphs and seeing the standard GTI putting out 260 or whatever power then the mapped car showing 330.
Rolling road figures vary remarkably from one place to another and the operator has a bearing on this too.
Tuners need to advertise so they like to massage the figures to make theirs look the best.
The only thing you should be looking at is the actual gain between stock and modified, not the headline figures. The latter can be manipulated.
You also want to know what development went into the map. How close are their settings to the tolerances of the standard engine and gearbox parts? How smoothly does it drive?
I’ve had over a dozen remapped cars in my time and all tunes are not equal.
I’m not one for watching YouTube vids normally and I’ve been to a couple rolling road days in the past, plus stood shivering with cold next to my own cars on the rollers when having custom maps, it’s normally a tedious experience!
The RRP vid was actually really well produced and filmed, it made a dull event quite entertaining, so well done to them for that at least!
