jetchip???????

Has anyone had a jet chip installed or know anyone who did it how and how much good did it do. On their web page it says you have to send your whole ecu then i would be without a car for awhile, does anyone know about how long? If anyone has any better ways to upgrade the ecu please let me know...i have a 93 ls i/h/e

Go to a local shop that does tunning and ask them if they can tune and burn you a chip on a dyno it is the only way to correctly set up the right fuel and igntion maps. Also make sure the ahve a wideband too.
