It’s likely the same reason the diverter valves they’re using are “reps” to hit a price point with the turbo to be competitive. Casting & machining those housings probably isn’t cheap, so they use aftermarket components for the rest, including the actuator.
Obviously a more aggressive tune/mods will ask more of the potentially crappy actuator, thus the varied results.
I think it’s worth the extra upgrades to make a good bolt-on turbo “kit” great.
With the Forge actuator & OEM electrical things, it should perform solidly. Plus, with the SoCal Porting port & ceramic coat, it’ll spool close to stock.
