Truck Repair: 6.9 & 7.3 diesel engines, fuel rail, computer chip

Question
Is there any way to turn the fuel up? The truck loses alot of power going up hill. Any way to help this problem would really help. Thanks

Answer
with these engines i think you can have the fuel rail turned up but a very easy fix to this would be to replace the computer chip with a proforance chip they start at around 75.00 and can go to around 300.00 depending on how much power you want to add.thanks for the ? and let me know how this works for you...
