Renntech.com has a performance package (pkg #2) for the W203 that adds 20HP and 27 lb ft of torque. It includes an ECU upgrade and a larger Crankshaft pully kit for $1,695.

Has anyone ever bought a Renntech upgrade and would this modification effect my warranty?

FYI: I have an '05 C230K Sport Sedan w/auto transmission (189hp/192 lbft).

Thanks!
