Went out tonite to test the g-tech, JL chip,filter & 90mm. Temp was 60, humidity 80% and no wind. Had to drive ten miles out to get away from traffic, and didn't let it cool down any. First pass, I pretty much fried the tires but still got a 13.9 & 103. Not bad I thought for regular tire pressure and no technique. Second time I warmed up the tires a little, and let her rip. Felt great untill I hit a 100 then it really flattened out! Any input as to what happened. Didn't hear any pinging or miss, it just went flat! Afterwards it seemed to be fine.
