I put Porken's ignition chip in my 928, and I have to say that it has cost me money.

-I can't keep a set of tires on this car anymore! LOL! Ken's chip made a definite difference. Around town the car is "snappier". It is a 1985 928S2, and has big-valve heads and longer duration cams than the typical '85 928, and prior to the chip it felt weak until 3000 rpm. The chip makes the car peppier at low rpms and non-full throttle operation. Just driving around town, it makes the car feel more powerful. The only downside is that you now HAVE to put premium in the tank, because the chip advances the timing as far as can be gotten away with without burned pistons.

I haven't run on a dragstrip in a decade, but I bet this chip adds a mph. The car FEELS faster- but make sure you put the best gas you can find in the tank.
