    assuming that you have tuned your car
    lower your timing 6 degrees

    make sure when you run it with nitrous your AFR is below 12

    Negative sir. Pull timing but keep AFR around 12-12.5 . Keeping it below 12 is old skool thinking. Now it's done by pulling more timing and leaning it out a bit more.

    to answer your direct question .. you only need to u tune the high oct. table ..

    ecu uses the low oct when it detect knock ..as the knock disappears it revert to the high oct ..

    most people copy high to low when they are in the process of tuning once they fished the return the low oct back to it previous setting..

    I would say the old school guys just didn't understand MBT as well as we do now lol... Not to mention we have nicer dynos too

    If your spraying 200 shot id go with the 2deg per 50hp of nitrous rule.

    Pull 8 deg and shoot for a air/fuel in the 12's. Nitrous is dangerous when run rich!

    Someone wanna elaborate on boost + nitrous? Is 11.5 AFR safe considering 15 psi and 50 shot?

    How about 1100 RWHP with boost and a little n20. If you look close you can see the wideband during the runs.

    nice vidoe guys ,,
    but i am not brave enough to make any Forced induction car with 12+ AFR
    i would keep it below 12

    as long as i tuned one of my friends car
    441 engine with 300 shot ,, and i had 780 RWHP spinning on dyno ,,
    and the car is still alive and he have run it more then 20 RUNS in the street + 5 on dyno

    i dont know ,, u guys might me much experience then me ,, but i hope someone explain his knowlge and feed us with information ,,,
    here you go the vidoe ,,
    sorry the vidoe is so bad ,, because i was tuning
    with low timing the car had 505 spinning a little
    should be 520 MAX

    300 wet shot 780 RWHP
