I'm looking for affiliates/joint venture in the USA.

Hello folks !
I am part of a nationwide company in the UK that enables vehicle engines to develop a little more power and produce more miles to the gallon, petrol and diesel. Usually we go to each vehicle and make the necessary software changes.
We now have a product that we send to the customer to allow him/her to decide what state of tune the vehicle run with, economy, performance etc. .
This is the 'nutshell' version of what I do.
There could be an opening for someone in the USA to be involved in promoting this device.
