A friend of mine saw it and said he saw a small blue flame, and it was loud as shit. I lose all my power, and I cant bring myself to do it more than a second to try to figure out what it is... Im taking my chip off tomorrow prolly to troubleshoot. People said maybe my optispark or valve timing, bad cat? I dunno... any ideas? It drives perfect exept at 5000. sorry for the long post.
