I have an Autothority chip for a 1990 Porsche 944 S2 for sale. I ran this chip for the car for a couple years before I had the car supercharged in 2002. I put the car back to stock with the stock chip early this year then sold the car. The car ran great with this Autothority chip, even here in CA with 91 octane gasoline - absolutely no pinging.
Here is what Autothority says about this chip:
"Our AutoThority chip upgrade provides your car with a 17 horsepower gain at the wheels and improved torque to go along with it. The low-end torque and throttle response are improved and the driveability is smooth throughout the entire power band. The performance can be felt right away as your car will speed through the revs quickly before reaching the raised rev limiter. The rev limiter has been raised 300 RPM in each gear and there is no top speed limiter. Our AutoThority Performance Chip is a simple upgrade and comes with full instructions on how to install it in your car. Price: $395.00"
I'll sell it for $195, obo. Free shipping.
I sold the supercharger kit on this sight as well, and also have a set of stock wheels on this site still for sale if anyone is interested. Thanks all.
Here is a pic of the sweet car it came out of:
