launch rpm

after a bit of testing I have found that my car likes 2200 rpm, 18 psi tire pressure( M/T ET street radial). It ran 11.77(poor burnout) 11.71, 11.69. 11.67 at norwalk this weekend. It seems to be where it used to be. Not really enough passes to say its consistent but i feel its getting there. I weighed in while there and found the car weighs 3450 with me in it, im 250. so, 3200lb iron headed 440 70 duster.
