    Timing question

    I have a Nelson tune, of course, and I want to say I have 27 degrees of timing. I just put a hsw wet kit with a single nozzle. I have the 100 shot jets in it and I'm not too impressed. I want to move up to the 150 shot jets, how much timing should I tell allen to pull with a retune?

    Allen will know how much to remove. I normally do 1 degree per 50 HP of nitrous. Some people do more, some do less. Depends when/if it knocks.

    Ok well I'll try to call him tomorrow thanks. Do you think I'll be more satisfied with the 150 shot? Because the 100 shot was kind of anti-climatic for me

    I never did a 100. I've done a 175, a 150, and a 125. I have a 125 on the 6.2

    How do you like the 125? And how much timing did you pull?

    I run 87 octane the majority of the time. I don't pull any timing, I just fill up with 91.
