I sent Marc an email regarding my 1995 corvette ECM, I couldn't find any accurate info about that, before Marc. He answered me really soon and gave me a great and right advice, exactly what I needed.
Thank you!!

Mr Haibeck’s knowledge of the ZR-1 is extremely helpful and he’s not afraid of offering to you.
