The rebel LS is a fantastic solution for LS swapped vehicles. Coming in at a very competitive price point. It would be hard to choose a factory PCM and modified loom option these days once you cost it all up.
Using the wizard they fire up real easy and are close enough that you don’t have to worry about fouling up plugs or washing out a bore. But they are far from tuned…
You can see here I ran the car up with no changes to the wizard generated tune up on the orange graph, and the blue one is after I finished up with it. With peak gains of 40kw or over 50hp to the wheels.
