[Biturbos4] Performance Chip

[Trask, Duncan]

Hey Guys,
I have a 2001 Nagaro blue S4 and I just bought it recently and I took it
to my mechanic to get it checked out and when he hooked up my chip to
his Revo computer it detected the chip but said it was not a Revo chip
so it could not do anything this is a little bit frustrating because I
thought I was driving my car with a chip and when he scanned it is
showed that it was in force to stock mode is there any way I can find
out what kind of chip I have with out going to every dealer around town
and getting them to scan my system?  Thanks so much
