Hello friends.
there are laws for us of the trade which protect you on the work carried out ?

if we eliminate a fap-egr closed-remapping , we make what is not lawful for me, apparently! (we pollute the environment, and change the data programming ecu)

For racing you can? to make holes in the ozone?polluting the environment?

and if a customer or a workshop jealous want to make problems, denouncing what we do!

how can we protect ourselves from these troubles?

customers are good and dear , but if we want to bad we bugger..

thanks to all
