Performance upgrade 05' e55
Hello Member's:
I wanted to know what other e55 owners felt would be the first step/thing to do to increase power on my car? ECU upgrade, pulley, transmission upgrade?
Any recommendations on company, i.e., Kleeman, Renntech (I am in the Los Angeles area)?
Do the upgrades in any way void out the warranty?
Thanks for your help

RennTech, Brabus, and Kleeman are the only three names you need to know.
Most bang for the buck upgrade right now is ECU... warranty will only suffer it's the cause of your failure, and then any of those "Reputable" companies will cover the failed component that MB refuses to cover. MB (under US Law) cannot just arbitrarily revoke your engine and transmission warranty for the upgrade.
