97 5110 8.6 17.1 16.6

it's mayhem and pandemonium!!!!!



bear in mind that the techs couldn't get a good tach signal and that is was 100 degrees with near 100% humidity - it was raining as well. I have to wait until I get better weather conditions.

The runs were made in 4th gear, 2k to only 6k... Terry reviewed my logs and said I should have put down 375-ish and their dyno (dynojet) was reading very low... new place on Saturday...... wheeee!!!!!!!
