the tps went bad so i replaced. the original one i modified to be able to adjust it an set to a .52 setting. the new one isnt adjustable either and is at .7. now i have a dead spot where i didnt before. since the regulator is a pain in the ass to get to an adjust i dont know what route to go. adjust either the timing or fuel pressure or modify the new tps..though i wonder if there is a reason for the pre set .7? and advice would be great. the motor has vortec heads and a CC 4x4 series cam
