very excellent reply buickmastermind; i never new such a govenor system existed. Do you think that the 90 lesabre would have the limit that prevents the motor from being held near the redline for long periods of time? I find it hard to believe that the computer could limit the engine speed so smoothly, unless it is dropping ignition to certain cylinders (like a MSD rev limiter does) instead of fuel. I would think that the 3.8 would just pull to redline in 3rd gear but not upshit to 4th due to the check ball. This thing is gonna annoy the hell outta me until i find out whats really going on.
