I just got an Innovative LM-1 which I am just learning to use but can say that if you have a modded turbo car, buy it. I am trying to set the fuel at 12.0 but that is not easy to do on the road. A long 5 gear pull would be nice but not realistic, so I might go to dyno.
I need to start posting picture of this stuff, unfortunately I do not have a service that will do this yet.
