I've heard that running a p13 on the f22 makes it run pretty good, i have yet to try it out but i will once i get my p13 back from accordhybrid. You can also get a p28 and chip that and run it, i used mine and had a friend burn a program on there which ran graet, except it was made from a race bin so fuel economy was not taken into account, i'm sure one can be made with decent gains and fuel in mind.
