I missed this moronic comment. The Supra was designed to be a GT car. It just happens to be good at high speeds because people tend to pick parts and tune for them have a small peaky powerband.
Did you just buy this car or did you have a shop locally do it? If so, do you mind saying who? You'd be the first person that the Supra community knows of that has a working 3.4L motor and the first person in California that's running 9's in a non race car. Just because HKS sells a 3.4L kit...
