Here check my recent thread review on Mega-Speed remap and a comparison to a piggyback (JBD) http://www.e90post.com/forums/showthread.php?t=724706

Chiptuninng Express is another variation of simple rail pressure trick controller as JBD that I had only more expensive for no reason. Both alters single rail pressure sensor and nothing else.
