Am really getting fed-up with this upgrade...a lot of headache plus I really don't have time for this...I spent many days trying to figure what could be the problem...that's end up here
I will uninstal the supercharger and return my car to original condition...this project is over...I will pack the supercharger and offer it for sale...any dam price and let it go...not my way of handling my lovely Z....can't stand many mechanics playing, testing, trying, driving it anymore...already many scarchs done by them and their dam tools...
Bye bye GTM supercharger
Thank you all for your great support and help...really appreciate it
