I had a local installer tell me that his Altima with a 8w7 powered by a 500/1 would literally STOMP my 97 Civic with a 1508 powered by a 25 to Life Punch 150. I showed up to take him up on his challenge and the first thing he said was "Oh, I didn't realize you had one of the new Punch 150s" then he proceeded to back down from his own challenge. While his setup sounded a little better than mine, there was no way he would have stomped me on the TermLab.
