Default trucks loosing power

my 12 valve is lacking a lot of power right now and i cant figure out what it is, i just installed a pyrometer and a boost gauge but the boost gauge isnt reading any boost at all, what could make this happen other than a boot or vaccuum line being off?

Wondering ..if you just installed pyro/boost gauges and you are now experiencing power loss ... could be you have a leak from installation of boost gauge through the tubing or the fittings?

my boost is running about 20 with the propane on and about 900 to 950 on the egt. i also installed these after i had the problem occuring to find out what was wrong with it. it used to put out a decent bit of black smoke and now theres nothing that i can see at all. i was thinking that it was either the injection pump or the lifters,,,,, anybody else have any ideas or how to tell the difference between the two??????????

Check your boost line running to your AFC for cracks or leaks.
