when i give my truck some heavy juice the psi will sometimes drop to 6, if i give it juice hard again it goes back to normal 10 wot 15 idle is my pump just geting ready to take a dump? also whats the difference between a regular cheap electric pump from the autoparts store, and a holly blue or bd pump?

 

The BD power Pump is about the equivilant (If i remember correctly) Of a Holley Blue! Bully Dogs fuel kit is a holley blue but im not fond of the kit!
A Holley Blue Will last longer than a cheapy pump! This is not an area to skimp in, And in all honesty, your better going with a Fass or Similar System!
It sounds like your LP Is on its way!
