The stift improver thing that plugs into the trany thats supposed to firm up shifts and increase line presure? Any one try it and what were your impressions. It'* sold on PCFY

We used to run one on the GTP, and 2000SilverBullet runs one on his 2000 SSEi. They work very well, they firm up the shifts, and are adjustable so you can have it shift as firm as you want, but they shift hard all the time, whereas an internal shift kit shifts harder as you hit the gas further. They are nice, but if you can put in an Internal shift kit, it would be better.

While we had it in the GTP we liked it though. AND, you can turn it up enough that you can break the tires loose when it shifts. If you don't mind it shifting hard all the time, it is great. I would definately not try to stop you from buying it.
