@drifter Its time you put the doubters to rest ( i know im included in the list ). Dont take it otherwise, but here's a sincere suggestion and an action plan. Take a Multijet FIAT ( Punto / Linea) and remap it / tune it/ put your AIR on it , i mean howsoever you like. Use your 4 methods of evaluation , 10 rides before and after AND document the gains achieved. Put it in black and white - hard figures, data : facts ( before and after). Put up the details here on TFI , everything ( excluding trade secrets ofcourse). Make that car the magnum opus of your tuning chapter in India. So that people know your work that much better and novices like me dont question your work now and then. What say mate? Gurjinder.
