Hello everyone,
Does a 6243 PCM from a 2004 Silverado 4.3L V6 have the necessary drivers/hardware to fire the extra 2 cylinders on a L31 350 swap with the appropriate tune/flash?
If not, will a 0411 PCM still be able to control the 2004 4L60E and communicate via serial bus with my 2004 Silverado gauge cluster?
Thank you.
