Finally got my truck painted and got it to where I can drive it. Running a 160 degree thermostat it is only running about 135 to 140 on the road on 90 degree day ive got a big aluminum radiator and 2 16in fans (guess I didnt need both) truck runs great but is this effecting my nelson tune or my gas gas mileage. Im running a 6.0 with 243 heads shaved .030 custom comp cam 595/608 232/240 @ .050 on a 112 edelbrock proflow intake with 42 lb injectors
