    LS3 crate engine E67

    Hey all, been out of this for a little bit (never was real good at it period) but i cant figure out why this crate engine will start and then die like the vats need fixed. I cannot find the vats in the ecu at all. E67 Factory Crate LS3 525hp.hpt . This is the factory tune with no changes. Any help would be greatly appreciated.

    Check MAF position, direction, and datalog for flow.
    This is usually the problem we have had with customers and those systems.
