    I don’t want to sound like a stupid noob, but, can anyone take a pic of how you put the adapter harness in the stock computer location? I just can’t get it to sit there comfortably with the factory harness laying like has for 30 years and the map and O2 plug easily accessible.

    Ive read that i should not rely on af ratio alone when tunning a chip. Obviously each engine has its own needs. here it seems like targeted af is what your concentrating on. Is this correct? Where do you get your targets from... seat of the pants? Dyno tuning is different, so do that after street tuning?

    I give a safe but very accurate target A/F in the startup tune. The customer can modify it to what they're car likes

    Cal, very complete kit thank you.

    My current 02 bung is longer than the one provided, placing the tip further out of the exhaust stream. Plus it is 24" away from turbo flange.

    Any issue with either?

    Thank you. I doubt it will be an issue. We'll know on start up.
