KB 2.2L...looking into the purchase of one of these bad boys running about 15psi, 560 rwhp, now for my questions...I know I will need 03 tank and pumps, but how does the boost a pump work, do you actually have to change the settings or can you just tune it in and leave it a one specific setting...same question on the boost a spark do I have to mess with settings all the time or do I even need the boost a spark...? will 42 lb injecters be enough for 15 psi or do I need to step up a tad...thanks I'm just trying to learn before I dive in...
