Well ive been on here since 2007, i started off with an
Ibiza TDI and then a Leon TDI
Attended many Rolling Road days, seen many different maps, Spent alot of time around Hybrid Turbo'd TDI's... im not in the business of maping or even car tuning but have been round long enough to know whats BS and whats fairly reliable
If you look at the likes of REVO they offer a map for this car thats rated to around 170bhp for stage 1, They obviously do some testing on these maps to know whats safe inside the oem hardware
So either this company is downloading a map from the internet they have know idea about and it will only put out 170bhp if that, he will sell it as a 205bhp map, you will test drive it and it will feel really good and you will think yeh ive got 205bhp
Or the map is a real pusher that will give you the advertised power but at the expense of the engine in a few weeks
