i was in your position and I also have a MY07..6k on the motor when I went FI; just wanted some low end grunt.. i got the greddy kit because i spent most of time in the 4-6k range..i am running 7psi for the most part.. it'll goto 8-9psi in 1st and 2nd gears at WOT

motor longevity/ safety was #1 to me..

if you are okay with a little less midrange grunt in exchange for top end power, i suggest kraftwerks high boost

 

And you probably don't care but I need CARB approval on an '08 application, seemingly pending by everyone.

 

seeing as greddy is carb approved for their 00-05 kit i think the 06+ kit, when it does come out officially (you can run a regular greddy kit on 06+ with some mods like i have), should get carb approval as well
