I've got a 60 Impala with an 02 LM7 4L60E combo. We just got it running a few weeks ago. I dont know much about tuning these computer controlled cars. I drove the car 3600 miles on the Hot Rod Power tour and HP tuners helped me with my tune, but I really would like to change the way the transmission shifts. The transmission shifts early and soft. At around 45 it shuttles back and forth between 3rd and 4th and cannot decide were it wants to be.
I would like to find someone near me who has HP tuners and can help me out.
Anyone out there?
