My name is Joe I am new to the forum and to diesel trucks. I sold my 73 chevy 454 that got 4 mpg and bought a 95 f350 crew cab 2 wheel drive 5 speed dually it is a xlt and everything works I just love it. I tow a 26 ft. PTD enclosed trailer that loaded with the racecar and spairs and tools is 10K lbs. I have installed a 3inch down pipe and 5 inch exhaust system, My next upgrade is a intercooler( I have an wanted add posted ) After that some kind of "chip" then a upgraded turbo impeller. I am a total newbe at this and could use some schooling. I have already bought a spyder that I cant use.I didnt know there is a difference in the 99 year model early or late. Thanks to all who make this site work.
