I'm pleased with the Conforti chips in both our cars.  I have never
timed them 0-60, much less before and after installing the chip, but
there was a noticeable difference in the butt-dyno and the overall feel
of the engine.  I understand the Conforti chip remaps the fuel and
ignition throughout the range, not just at wide open throttle.

Ummm, try 2800+ and 3100+, but you've got the right idea.  And you're
looking in the right places for improvements: weight, chip, and final
drive ratio.

We use Mobil 1 in our engines, Red Line MTL in the transmissions, and
Red Line 75w90 in the diffs.
