    Wideband

    Can someone tell me on a turbo car are they running their wideband sensor before or after the turbo and pros and cons of each? Thanks

    Must be run after. The pressure skews the reading if installed before.

    I have mine about 26-28 inches away from the downpipe connection, just wondering if there were benefits to before as in my mind it would read the engine AFR which may be different from what you get after turbo, heat etc. it is my brain wondering what if, not that any of the above is true just the logic being applied. Thanks
