If I turn up the pump for more fuel, do I have to make any other adjustments? And as for watching the pyrometer, I don't have one installed in my truck.Is it worth putting in a older truck?What is the normal reading for exhaust gases,or a limit not to go over? And is it normal for my truck to be screaming at 50 mph? I have a c6 trans in my'87 4wd. I used to have a '96 7.3 w/turbo,and that could run at 80 mph all day. Just want to know if that's normal. Thanks, Jack
