    Just not doing a burnout. :lol:

    Trying to get the tune dialed in. Justin is having me do some data logging. I am getting a lot of spark knock and it's pulling timing through the rpm range but really bad above 4800. On this pull, torque was basically the same as last time and horsepower was up 15-30 down low, but once it got above 4800ish it started pulling timing and hp fell off. Only peaked at 426 this time. Probably going to have to put cooler plugs in it.

    Maybe, but I don't think I really should need it with 93 octane and only 7.5-7.8lbs of boost. We'll see. I'm still running stock plugs. They may just be too hot for this much boost.

    Yeah but are you really going to be staying at that low of boost very long? :devil:

    I was getting a good bit KR up top too with my stock plugs. I went one step cooler and its almost gone. I blame the rest on my tuning.
    What AFR are you running nominally, in PE and in Boost? I set mine at 13.9/12.9/11.5. I'm getting decent mileage not in 'boost'. I want it leaner without burning out my exhaust valves.
