I've only use two engine dynos since I move up here to Bend, OR . The one I used in Madras may not be available anymore as the owner died several years back and the guy that was running it for him doesn't like me anymore
The other one is in the Medford area of southern Oregon, Lindvigs machine shop and dyno service in Phoenix, OR between Medford and Ashland at the bottom of the grade coming from CA on the #5 freeway.
Dean seems to keep his current with all the software upgrades as they come out
PM me on here for more info if you want how to contact Lindvigs
