I apologize in advance but your post is mostly ranting!
these days ecu chips in USA are reflashed using custom software; chipping is outdated. that is number 1
secondly; have you been informed of the HP gain? torque curve?
It may be jsut increase 4 HP and you have spent about ( i guess) 22,000 Rs. am i close? :-))
so what is the price /Hp?
all you need is some experience some tutorials from you tube and the OBD flasher and software worth some 2-300. rs. and you can do it yourself.
some rich guy opens up expensive shop in expensive city and we all go excited.
until you mention what is HP gain? there is no point in this write up
