Does Jim C. make a chip for the 1994 540iA? How much of an improvement does it make (IYHO of course and I know that MMMV also). I'm in the process of buying a 1994 540i and this is one of the first mods I'm looking at making. Any other suggestions for this car? I love the way the 540i runs compared to my 535i. TIA, Tomas S.
