communicating in July 2011. i saw one e-mail from Jan 2012 about you using a nistuned ECU and a Z1 auto trans etc. Instead of e-mail would you prefer calling me ? 941-302-9800. If that e-mail is any indication you have a loaded question that cannot be answered in a short e-mail. Please call in the AM after 9 am and i will be glad to assist. FYI to make a LONG story short IMO you are a prime candidate for a custom tune. I can explain the many reasons why in the phone call.
