Another '04 Granite With 460 No Power
in Engine and Transmission
Posted
This is my sixth week with this truck. E-7 460, 18 spd, and 4.73 rears - thought this would make a nice lowboy truck. I love everything about it except the motor, slow throtle response kills me on any hill. Boost will get up to 32 psi once the rpms are 1600 and up. I understand being slow with a heavy load (almost always 100k - 130k) but even empty it falls on its face. Also throwing a 8 - 4 code, but only at start up, light will go out after warm up. Im hoping this is my problem but open for any suggestions. Maybe a hotter program?????
