Horsepower is addictive.Four day old E55 in the garage. Have not seen this kind of power since I drove a buddies 409. Powerchip makes some fairly hefty claims for just a computer change. Any of you folks tried them. Thanks.

I did a RENNtech upgrade - chip, pulley and belt upgrade on the supercharger. Major increase in HP and torque. I suggest you look at RENNtech, or KLEEMAN, who have a more comprehensive approach. I suspect it's safer.

Thanks, Stupid question, think I know the answer. What did the modification do to your warranty. Talked to Kleeman people in Atlanta and was advised I had to purchase a whole new warranty for $5000. for the entire car if I did any of their mods. Thanks again.
