with the stock 3.15 and converter you dont need to go below 28-30....i run mine at 30 and never had problem to hook...That's new to me. I run 28psi on the street and at the track I ran 18 and it was dead hooking, I have the A6 tranny with 3.15 gears and stock converter so when I go to the track this weekend I will try 28psi and see what happens. It was dead hooking with a 1.94 60' not good and I was getting that on the stock tires. So gonna see if a little wheel spin will help get the turd moving
