i made several test hits and fortunately a couple of well known chassis builders watched the car and helped with shock adj. and tire pressure.Went 1.37 ,1.36 and 1,35 60 ,9.74 best.My incrementals from 330 on are very good(330 to 660in 2.17and 660 to 1000 in 1.90 but i am .14 slow from 60 to 330.There consensus is get new tires with a softer compound and the converter is too tight.So i will order tires tomorrow and hit the national ope at sacramento in a couple of weeks.
