Review test results as to when we did a custom tune that was biased for engine to run lean to save fuel but make use of our water/meth design last fall.

After several months then here is results of testrun today.
Weather was 60 degrees, 3600 feet elevation, gas is 91 octane with 10% ethenol.

Along with being lean part throttle we also set WOT timing at 29 degrees yet with tune calibration there was zero knock or misfire with engine compression at 11.3:1 of this 372 stroker LS1
