Why not ask Matt (Custom Car Grills) and ask him ... sorry, my comment was not meant to be sarcastic even though it may have sounded that way :) ... put a question within his section and I am sure he will asnwer ... at one time, he was willing to 'work' with someone who was willing to get and before and after dyno :)
