folks use 'em. folks will use yours too. Hell, I may even buy one of yours. I will also guaraneffentee you not yours, not JWT or Devin's will blow anybody's car up. All three WORK. Yours is more efficient. I "may" even notice a difference! Like I said, not interested in #s on a dyno, don't race, could'nt care less about going past 15psi on stockers. Hell the way I drive, I could've probably kept the stock chip! Just pointing out you and JWT aren't the only "Players".
