WTB: MarkD chip. JimC trade?

[Jordan325iC]

I've got a JC chip in my 89 325iC, but seeing as how I'm running 93 octane gas, I think I'm selling myself short by running a 91 octane chip. Therefore, looking for a 93 octane markD chip for my 1989. I can buy it or trade my JC chip.
Thanks,
Jordan

When you find a new one how much would you sell the JC for?

only some of them were made for 93 octane

Last I heard MD hadn't made any 91 octane chips. I guess I'm out of the loop.

I'm looking for about $125 shipped for the JC chip.
