Fuel pump mate deffo, it's took about 0.4 seconds from my 0-60 time, I've still not done a 1/4 mile to compare times but I'll post the results once I do.
I've got the same mods as you near enough, and I noticed the giac map was a bit on off boost on with out the pump but the addition of the hpfp has smoothed it right out and beefed up the midrange shove !
