Impressive for sure, but the thing I really hate about a before and after graph is that you really have no idea of what the engine operating parameters are for the two runs. For example, you could do a pull on a warm motor with good IAT and coolant temp and get some excellent numbers. Then you could do a pull when hot and get crappy numbers after the PCM pulls maybe 12 degrees of timing due to coolant temp and IAT thermister cooking. You really couldnt get an accurate idea what the part did to improve performance, at least if you werent monitoring these areas. I'd like to see a dyno chart with some readings of what the PCM is seeing as well. Nothing against these rockers, but I thought I would throw in my .02.
