what was the point of this thread? to bitch about knockoffs?
No one is aruging the better performance Gruppe M offers over stock, we know it does do something after ksfrogman's dyno runs, so again, what is it that you're going on and on about?

If anyone wants to see any other test results then let me know. I will try and get it done.
