"Anyways, my offer still stands. Anyone who wants to drive my car can and perhaps they can do a comparison themselves. That might solve all of this, or at least help."
First let me say that I am quite pleased with the Autothority chip in my 2.7L Boxster, not that much increase in peak HP, but very responsive. That being said, I dont know how useful having someone drive your car will be to demonstrate how well your chip works.
Here is my reasoning, I recently testdrove drove a 2001 2.7L Boxster with 63K and a 2000 2.7L with 43K. There seemed to be a very noticable difference in responsiveness and power in the 2001 car, even though it is supposed to have the same engine and HP. The other example I have experienced is my car and a almost identically setup 2000 2.7L Boxster.
Same chip, exhaust, intake, just different wheels. The other Boxster was much, much more responsive (could break the tires loose pretty easily in first gear). So I may be hard to tell how much of the difference in drivability is just inherent in your car,
Cheers,
Ed
