I have a 1995 ford f350 cc 2x4 PSD 5speed. 4.10 gears k and n filter, 6 pos. chip (stock, 50, 75,100,140 and high idle) egt,water temp, and boost gauges, 3" downpipe straight exhaust. I am grossing 20,000 with my truck and camper. The hill around here that is the test is a 7% 5 mile grade. I want to run between 45-60 mph up the hill. Is it anything i can do to help without breaking the bank? the truck has 170,000 on it. Should i do the DIY injectors or are they not worth it in a high milage truck. Should I just get new injectors. I cant do it now but may be one day. please help.
