LOW EGT Readings

[nickg]

Looking for ideas...
I'm low in the power dept
I've adjusted the valves
did the Quick/dirty Timing chain stretch thing and it looks to be about 4-5degrees out
I have an EGT gauge installed where the EGR used to be hooked to the exhaust manifold.
the ALDA is backed out fully
truck has 4:56 gears and weighs half of the sd that the engine came from
banjo/tubing from pump to intake is clear
Boost shows I'm making up to 14psi
New fuel filters

truck is sluggish off the line and seems to have no acceleration

the kicker is NO BLACK smoke under load (WOT) and the most I have seen out of the EGT gauge is 700F at WOT at 70MPH normally driving around town, again at WOT the most I've seen is 500F. I believe I dont have enough fuel being delivered....
any thoughts??
is it a bad pump? or can I tamper with it and "fix" it? or is 5degrees strech enough to cause these issues?
