Bro, can you please stop taking passive aggressive jabs at anyone running a JB4? Its uncalled for and is getting annoying.
You also keep quoting other members unverified comments as facts even though most of them are incorrect, or have already been disproven. The JB4 on its highest setting, Map8 doesnt even hit 19psi.(Log attached at bottom for proof). While almost all dyno's directly from lap3 show 1.32-1.5bar(19-22psi!)
Lastly, your other posts contradict you own statements. When did you hit a 12.0 with "just Dp's and intakes"? You just explained that you ran a slower 12.17@116, but that was with both primary DPs & SSR midpipes, and believe that was with e30 too.
I think you need to clarify what "more & less" means in your final statement. From the facts you provided, it looks like you're paying almost DOUBLE

= $3000(lap3~$1200, DP~$700, SSR~$600,
Injen~$500) and running more boost, but getting less performance than Kato=$1750(JB4/WMI~$1100, K&N~$400, VT~$250) and many other JB4 users.
Nothing personal and glad you're happy with your setup, but please stop trying to convince others the lap3 does "more with less" when all the facts show otherwise.
