And at 7psi.. you'll be pushing the limit of 370cc injectors with a t28. ~9-10psi on a t25. So, my reasoning on not needing a boost controller during the ordering parts process. Later, have a blast with it once you have the setup/fuel to support more pressure.

Jeff's right. I'm thinking too generally.
Get some bigger injectors a fuel pump and a boost controller. =)
Although I've seen quite a few SR guys running 370s on 14psi of boost with just an upgraded pump... I wouldn't recommend this though.
