Well, after more than two years of mostly grazing in the pasture. I got the E85 tune where it drives and cruises real nice. I also changed some suspension pieces. And long story short got to KCIR yesterday on plain ol' radial tires(no vht either). New best (without slicks) .490 on a protree/1.79 60'/4.93 330/7.58 1/8 mile. I was floored! This is just the way i been cruising around in it.
