okay guys i need some assistance. a friend was trying to tune my car this last weekend, we thought we had everything right before getting it on the dyno. i tried the first pull and it bogs around 4k rpm and says its running super lean, he decided to give it more fuel and tried again. well we repeated this a couple more times and it never helped. so my question is does anyone know what could be causing this? im running a msd and thought that was maybe the problem so we bypassed it and it still does it. im going to change coils, make sure i have voltage at the secondaries, check the fuel pump. any other ideas or things to check?

my setup if you want to know:
streetport
t78
walbro pump
stock fpr
msd booster and stock coils
