sounds like fuel starvation to me. Nothing in first gear then all through the second half of the track. What kind of fuel pump?


Yep. Fuel issue. Just because you have good pressure doesn't necessarily mean the motor isn't starving for fuel at the big end. Ignition, valve springs,etc, would most likely show up in every gear.


Went through a similar situation w/fuel pressure remaining stable but still didn`t have the VOLUME so after I installed a real pump(Magnafuel 300)problem solved and picked up a bunch of et and m.p.h. That`s just one of the several things I`d be checking as others have stated..........Ditch the Mopar ignition crap also.......... Also, was that your shift light I saw in the scoop that was covered?
