Hi guys, I have been wanting to get my S3 on a 4WD dyno for some time and have been doing a bit of research to find a suitable dyno relatively near to where I live. I've come across Monster Motorsport (http://www.monstermotorsport.com/) in Loughborough who charge £50+VAT for 3 runs for an individual, but offer discounts for a group. If you'd be interested in this, please PM me and I'll get it sorted out. They are open week days and Sat mornings, which would be my preference. Cheers, Paul.
