NiteWalker

I am sorry, my Lex is a 02 GS430 White and bone stock (hopefully not for long) B)

I am new to the whole Lexus thing but I will tell you this is by far the best car I have had. My question is where can one get aftermarket parts for the beast, I have checked a few places and all they have is springs and shift knobs. I am looking for and ECU upgrade; help me provoke the beast even more... NiteWalker...
