Fuel Injectors 028015619
I have changed the spark table to max out around 36 degrees and currently am happy with the acceleration and no detectable knock running 91 octane gas. This changes has made the motor run better when accelerating from no or light load all the way to a 4500ish shift point.
If anyone else needs help with a NA 4.0 / 4.6 let me know and I will provide what information I can.
