Just thought about the comment about the newer 06 & newer head flows 50% better on the exhaust, efi-diy,,you stated it will help w/the turbo spool up better.
I disagree,ports being bigger ,less velosity,slower spool up.
A few ways to bring the spool up is by Nitrous,smaller turbine housing (I recommend),or a loose converter,not being a BB turbo,3500 stall is aprox the min. stall needed,that's if you want to be able to boost launch. Two cents thrown.
