Trying to find out more about NCK Racing who used to work out of Mallory Park in the late 90's from my searching it would appear to be related to Graham Nash The Duchess had a gas flowed head and manifold along with "NCK sports Pak & chip tune to 6000rpm". I've yet to open the ecu to see if it was changed out or not. I can't find out any specifics and the invoice is s vague as my description. The only other reference to the sports pack is on a Marcos site where the owner had the same upgrade applied to it.
Does anybody here know any more about what they did in respect of the tune, like ferkle with the existing chip or replace with another?
