    Damn that's hot. I wish I had that under my hood.

    How did you kill your cat with your S/C?

    The 2003 S/C was not originally designed to work with 2004s. David even called TRD on it (he obviously ignored it). Anyway, there is a 2004 piggy back available now, but when David got his S/C they only had 2003 piggy backs. So for a period of about 2 or 3 weeks, David's engine was pinging like mad under more than 50-60% throttle. So he got the UniChip, which the company claimed would take care of his problems. Well, they were wrong. They had dynotested the UniChip on a 2003 S/C Corolla (blk03corolla's in fact) and had also successfully tested it on a 2004 N/A Corolla, but never on a 2004 S/C Corolla. As a result, the fuel mappings were still all wrong, and David ran like that for another week. So all told, David's S/C has been running improperly with totally messed up fuel timings/mappings for over a month. The problem was finally corrected after retuning the UniChip at a dyno shop that UniChip paid for. Still though, that leaves the one month of incorrect fuel. That's what killed the cat. Or to make a pun. David's curiosity with a 2003 S/C on his 2004 killed his cat.

    hell. It looks like my twin

    That sucks on your CAT. You'll have to let us know how the magna flow cat performs. Hey Hooolala, do you have a boost gauge on your rolla? I want to get one but don't know which one to go with. As I understand, depending on the manufacturer, I have to fit a barbed nipple :D to the S/C and then clamp the Boost hose on to it. Anyway I'm slightly retarded when it comes to understanding all the lingo.
