    Question VTT stage 2s installed! But I'm having misfires?

    What's going on everybody?
    Well today I've finally got my VTT stage 2 turbos installed, but now I'm having multiple misfires on 1,2, and 3 cylinders in addition to a
    2C24 Lambda problem in front of catalytic converter, muddled, which I'm not sure how that happened unless the o2 sensors where switched or something. As far as the misfires go, it only happens within the first 30 seconds of start up and then everything goes normal. I'm not sure what the cause of that could be. I'm going back to a shop tomorrow to try and troubleshoot and finish a few other things. Any suggestions?

    Mixed up O2's can cause ALL kinds of problems. Make sure they got them right.

    Ok we're going to double check everything in the morning and get back on the road. I'm hoping that's the problem since we didn't touch or replace anything else.

    Well I'm back in action! It was a simple o2 cross up on the first bank. Now the car pulls harder than ever! The only thing I'm waiting on now is a INPA K+CAN K+DCAN cable, so I can use Wedge's flashes to truly wake the beast from within and then its game on!

    The INPA cable is for coding the BT cable is the one you need to flash.

    Yea I know, but my original bin that I sent, Wedge, was bad and out dated. So he's going to update my firmware and send me one of his files so I can open it up.

    The car is running good now. I'm not getting any misfires any more. Now the only thing I need now is a proper tune so I can really open it up.
