I do suggest if you buy a PBX buy used. Plenty out there second hand for $100-200. $300 like I paid isn't worth it. Put that money towards the PE. Now with that I AM HAPPY!

By the way, also look into the AA tune. It is the only proven (through dyno) mod that will gain HP. I've read some very good reviews on it.
This. AA tune or nothing.
