I'd imagine nothing but good will come of running them on my 11.2:1 compression 3 liter, or in Worldtour's (or anyone else's) SC application, but on anything else gains would be minimal. Some of the people with chips may notice a gain alos due to some of the programs being overly aggressive with the timing...
