IMHO, Steve is the only way to go if you want to chip the car. All of the other chips are cookie cutter, ie every '84 gets the same chip, etc. In addition, Steve will not increase the rev limiter above the Club Sport limiter which is 6800 (stock is 6450) unless you specifically ask him. Autoauthority chip goes to 7k which will eventually cause rod bold failure in the 3.2.
Steve's chip basically tunes the air fuel mixture and timing taking into account the fuel and other mods, if any, to a point that Porsche would not, and could not do.
I have given the car a pretty good work out and have not detected any knocking or pinging, at the high end of the rev range or when loading up the engine at the lower Rs.
Just remember . . . . you will need a roll bar to track that thing
