I love my p-pump, but I would almost have to say the CR. Don't get me wrong, you can make awesome power with the p-pump and it is proven. The CR gives you the ability to from 400 to 850 with the push of a button, and gives you awesome drivability. Reb's truck does 893 and get 24 mpg, thats hard to argue with. Actually, i think it comes easier on the CR too. All the power on Reb truck is done with a stock head (untouched), stock head gasket, stock cam. That ain't gonna happen on a 12 valve.
