wow, i don’t know how i missed this thread. dozr gave some spot on advice. my car is currently stock aside from the 2.5" mufflerless cat-back. i don’t plan on doing any mods until spring because i am more concerned with school right now. i am planning on power plus 520 injector nozzles and rocketchip’s euro stage 3 software.
i have been up and down on whether i want to use biodiesel. i just talked to a guy with an old benz that is running it with no regrets. he skips a few steps in the process of making it too, which is tempting, but i have no desire to break my car. i would really rather buy it from a company that can produce it under greater control than what i can do in my garage.
GL with it and enjoy!
