 Trustindex verifies that the original source of the review is Google. Very pleased with the work that Alt Tune did on our 1.8 BMW X1 Diesel.
The car runs so much better.
Power and acceleration have markedly increased.
Thanks to the Alt Tune team.

 Trustindex verifies that the original source of the review is Google. This was an amazing company to steal with. I dealt with another company that stuffed up the tune in my Ford Everest that bad that I didn't want to drive it any more. However ALT Tune fixed the issue in a quick and professional manner that sorted out the problem and makes it a pleasure to drive again.
