If you're looking to launch your Gen V, Direct Injected GM vehicle off the line on a 2-Step rev limiter, MSD part number 87331 is the answer. When activated, the 2-Step will hold your engine at a constant RPM. This can be achieved by way of a clutch switch or push button.

The rpm is adjusted with two built-in rotary dials ranging from 1,800-9,900 rpm in 100 rpm increments. A handy LED shows when the launch rev limit is active.
