E-mail with instruction manual has not arrived - only reason for 4 rather than 5 stars. Actual reception, installation and explanation excellent. Difference that Stage 1 has made to Q5 is way beyond the numbers. It just keeps on going, effortlessly, and no negative impact on MPG.
APR had a problem with their server. It is supposed to auto send you an email with your upgrade information after I flash. I will make sure I entered your email correctly and send you the packet myself. Thanks for the review!
