Improve the performance of your Vortec by installing our high dwell Dyna-Module! Dwell within the module controls a coils saturation time, which is the time needed by the coil to produce a spark. The dwell in our Dyna-Module has been increased electronically to provide the coil with additional saturation time. The result is a more intense and longer duration spark in the combustion chamber that will improve throttle response and low end power! Installation is easy as the Dyna-Module mounts in the original factory location with no modifications.
Fits Vortec 4.3 V6, Vortec 5.0 – 5.7 and 7.4 V8. Also fits 94 – 95 LT-1 Corvette, Camaro Z-28, Firebird and Trans Am.
