Overheads. :-)
We are a small company with 5 staff where revo has many mouths to feed and a huge marketing budget.
We constantly update our maps to move with the times and ageing cars, we are now on generation 3 mapping for the tfsi, to take into account weaker actuators ect, we have spent many ours working on brand new throttle load maps which are based on Porsche 997 turbo mapping, which gives the driver a linear throttle at every rpm range, unlike the factory dbw mapping which makes the tfsi feel surgey or all or nothing throttle. We are the only tuner who offers linear throttle mapping for the 1.8t and 2.0tfsi engines.
