I have been searching but have found no answers. I have heard the msd dis 4 will not work on an ls1. I know the factory ignition is great, but I would like to have a 2step rev controller for the track and the ability to adjust the timing for a hit of nitrous. The guys at More Performance say my tune should be safe for a 100hp shot, but if I want to run more I would like to be able to adjust the timing myself.

for the two step check the harlan unit. As for the timing I dont know of any other way than to buy a tuning package such as HPTuners
