Well, after driving for 4 months with the programmed FICM, I have to say that I am wholly disappointed with the product. I have not noticed any improvement in throttle response or mpg.
I do see now that there are some other options for the tunes and am thinking of trying one of them out. Can anyone tell me what the differences are? I have seen the graph, but I need to know what the downsides are. If there are no downsides, why would anyone choose one of the less powerful options over the Hercules?
