All the extra tech is just something to break. Does it make a little more power, pollute a little less, sure.
But IMO its not worth it. Costs go way up, simple is usually better.

The secret is a 2.56 Safe-T-Track that I installed about 15 years ago. With the 3.36 gear, it got about 16 mpg at 65 mph.
A buddy who drove part of the time was impressed with the TORQUE the Pontiac engine produced. He was amazed we were able to maintain 80 mph and pass cars up long steep grades without as much as a downshift. The LS engines don't have the torque of the old Strato-Streak Pontiacs. And torque rules on a street car.
