I installed the Hypertech power programmer III , a year later I changed the rear gears to 3.42 ,then tried to enter that change into the program, the programmer always said code 8 and to restart, it said this over and over 4-5 times, I gave up, and thendiscovered the engine wont start at all. what now?

I also bought Hypertechs power chip for my 91 caprice, Hypertech did not disclose the 85 mph speed limit and they refuse to take it back and they refuse to return my $200. Suprising Busioness ethics... thanks Mike Thomas
