Another vote for Keith/KDI. I just did a fully ported blower/snout, everything...$1390+ shipping. Keith was the best, awesome service, got me the new blower exactly when I needed to have it (I did the install while on vacation for a week in the US) then got me my credit within minutes of getting my core back.
I've mated it with a ported LS7 TB and NE intake. Also have a LS9 cam, 8.6 lower and 2.5 upper, datalog shows the max boost went from 15.66 to 16.38 so it might be time for something more than a stock exhaust.
Cheers, Paul.
