i've got the a'pexi vafc, dsm 440s, and a drag inline fuel pump on my '94 auto accord ex... there seems to be a hesitation in power at full boost around 6 psi... not sure if it's the tranny or if it's something else... my dyno graph shows hesitation after 5000 rpms and im running a little rich (goes from 12 to 11)... i found out from a'pexi that their vtec controller doesn't work properly on 4 cyl accords... so i rewired the vtec solenoid and vtm wires back to stock... car seems to pick up better but still that power lag in the high end... any ideas..? should i take out the inline fuel pump and retune?

I don't think you NEED the pump - if its running that rich why don't you lean it out sounds like thats your problem, if you can't cut enough fuel with the afc lower your fuel pressure tune it again or get rid of that pump and tune it again.
