I've got a 1995 chevy tahoe with a 5.7 TBI motor and a 4L80E transmission, I was wondering if anyone could point me in the direction of an ECU upgrade module that plugs into the OBDI port inside of the car. If no one can, then can some one give me some info on installing a JET performance ECU chip?

If you are a bit of a techie, you can start here: http://www.customefis.com/links.html You have to have some special bits of equipment and a pc, but you can program your ECM. (not via the OBDI port) Otherwise you can follow the rather simple instructions provided by Jet for the installation of their replacement chip.

Are the Jet chips any good?
