Q:will this increase fuel mileage
A:This MSD Ignition Launch Control - part# 8733 is not designed specifically for fuel efficiency. This MSD 2-Step Launch Control is designed for GM LS Series Engines with Coil-per-Cylinder ignitions. It can be used with 24x or 58x trigger wheels. The 2-Step Control will provide consistent launches and quick 60-foot times. RPM adjustments are made via two rotary switches located on the harness side of the unit. The adjustment range is from 1,000 - 10,900 rpm, in 100 and 1000 rpm increments. The LED will illuminate when the launch rev limit is active. The engine rpm must drop more than one third of the set launch limit in order to activate. For example, if the launch limit is set at 3,000 rpm, the engine speed must drop below 2,000 rpm in order for the launch limit to become active (one third of 3,000 rpm is a 1,000 rpm drop).
