that is what I am leaning to (well that or a fuel line restriction restricting flow, but would think that would restrict pressure somewhat also) but have no idea what idea conditions are for this, with my 3000's I build I have a full stand alone ECU in them I can watch everything and know what it should be doing (as I am the one that had to tell it to do it) with this I have my old trusty Snap-On brick but it is slow and I really don't have anything to base the readings off of

is there software out there that can be used for data logging? tunning?



again thank everyone for their inputs ANY idea are appreciated
