I Think Instead Of Putting In 720 On Stock Turbo Your Next Upgrade Should Be Gslse Injectors. After You Do All The Modifications Then Do The Big Injectors. I Am Running 720s On Primaries And 1600s On Secondaries. I Think The Best System Is Sakura Nest To Haltech. Sakura Is Now Being Serviced In Tampa Where Fisher Buggies Is. They Have A Dyno And Everything. System Is About The Same Price As The Microtech. But You Get Better Graphs And All This Other Crap. Let Me Know If You Are Interested I Know The Owner There.
