The PE will add about 100 horse at the push of a button via more fuel. The EZ will advance the timing and add more fuel in as well.
The PE will deliver more fuel only. The EZ advances fuel injection timing which is purposely retarded at the factory for emision and power purposes. I highly recomend the EZ as a first time mod, or your only mod.
If you wait, I think they (EDGE) are putting a box togather that is a PE and EZ all in one. Good luck.
