Get 60's,raise the fuel rail and use injector adapters.You want to oversize injector's,not use injectors barely enough.

Those are 35#ers... IFR at 0 vac = Flow rate at GM differential pressure (58psi).

On his 2007, they'd flow 57.7#/hr at atmosphere. At 8psi of boost, he'd flow no more than 53.6#/hr.

Yea, i probably didnt need 96#ers but they will idle like stock with the versafueler, I hear that the large 60#ers (high impedance) are sluggish, with poor throttle response and a ragged idle.

Thats why i went with the Versafueler.
