7x.012 to 6x.015 difference?

My experience with "flooding it" at the drag strip has been a learning experience. Never have tried anything but 5x5, and when building boost, easy on throttle, building boost as I roll to the lights is how I do it. On hot days, 95degree plus, it's real touchy. Just a hair to much throttle and it bogs won't build, lighten up on the throttle and it will slowly build
 
I went from a 7x.012 sac cpp injector to Weston's 6x.013s used from Jlbayes. Not much differnce in csa between the 2 at all, but both act very different. The 7x.012 were more friendly on the street, Less smoke under the chargers, quicker spool, but the 6x.013 smoked much less heading down the track, netted 1-2 mph trap speed better. Overall boost pressure has dropped from 70psi to 65psi, but quicker 1/4 mile makes me believe the new injectors helped my drive pressure (no gauge) and the turbos are working in a better range and happier with less psi
So I believe going to a .015 should feel a difference
