Velocity stack changeout
2015 Z51, LT1. It's so bland under the hood, wondering if a velocity stack setup is available for this generation. Hood clearance problem or maybe side stack? Heard these setups in general are not easy to tuneup. pros/cons?

I wouldn't hold my breath, Individual throttles/runners usually require a completely new airflow model based on "alpha-N" speed density. This would not only be a packaging challenge, but the ECU is NOT going to like it when it still has to be a torque based control system. The torque control system (that also controls the trans and traction control) relies heavily upon the ECU for aircharge and torque estimates which will be radically different in this layout. In all honesty, you'll make pretty much the same or better power with a traditional single throttle/plenum intake manifold and still have a sporting chance at keeping the electronics happy.

I bought a Harrop setup for my old C5Z. Those types of intakes look great. It could be done and easily fit under a C7 hood. I bought mine for MAX hp as it was a NA 416” motor then going LS 454 ci. Big power gains a d existed ring the last bit from a combo is why most use these
