    Increasing power and torque effectively increases the numerical gear ratio value when compared to a stock engine. I call it the "cheater" method.

    Much as I despite my Revo tune it sure hits hard on the torque.

    Should be going head to head with a 550hp Jag next week or two. I hope it's a cold day.....

    I am now using Amsoil Octane Boost with each tank. Bought a case last week. Impressive stuff- normally only use it during the summer. It's like my boost is back to where it was before lowering. Might try 2 bottles when the Jag is ready to play...

    I believe one of the advantages of the 5spd gearing is it's very well suited once rolling. Would predict if gearing was reduced (higher #'s) too much the car would be significantly slower. Unless it had more cogs to grab to keep the engine loaded.

    For a drag strip queen would certainly focus on getting the car launched. That's how the new cars are so fast off the line. Short gearing for impressive 0-60's. But at speed the Ol' C5 walks them or is in striking distance.

    Drove a 650hp Shelby (595 whp) I worked on years ago and it didn't feel much faster than the RS.

    And after driving a MT6 RS6 conversion was a bit let down. Stilly short 1st gear. Car was down on power so was like driving a NA S6. Thinking if a newer Autobox would fit (someone chime in?) that would be the ticket. D
