The last time I was at Summit Point (almost 2 years ago), the AutoThority guys were there testing and tuning a Porsche for the On Lap Of America race. It was a very fast car! If they are making a chip for the 330Ci and the M5, they're are probably pretty good ones.

You said got a 14 hp gain at 5000 rpm. The rated peak HP of the 330Ci is 225 at 5900 rpm. What was the peak HP of the "chipped" engine and at what rpm? What did the torque curve look like? Also, what is your "seat-of-the-pants" evaluation of the performance gain? Finally, do you know if they are working on one for the E46 ///M3? Thanks.
