    White exhaust tips bad??

    Ok, so only my left exhaust tip is white. I checked the plugs and they all look the same and they don't look like they are melting. I'm running a 125 zex wet kit and I'm not getting any KR. I'm not going to hit the spray again till I get my wideband hooked up but I was wondering if I should plan on bringing my car into the dealer for a new engine. BTW, I'm running .003" larger fuel jet than zex recommends and 12.7:1 commanded a/f ratio.

    Umm, clean it and see if it comes back. Could be anything including road grime. Got pics?

    ah, its definitely not road grime. I'm gonna clean them and I'll let you know if it comes back. Car still drives fine. I'm gonna get the bottle filled and tune it with the wideband.
