I am looking to put my 400 trailblazer on a dyno. I have a friend who has one but it will only go to 40hp at the max and i dont know if i have more hp than that or what would happen if i maxed the machine out. And is there anywhere near Liberty, In(just below Richmond) that would put it on and help me tune it, or tune it themselves, For cheap.
Any Help?
Thanks
