Well, it goes like this i have a 98 Gt that has a p-1sc supercharger kit on it. The mass air that i have is a 80 mm pro-m blow through style mass air. However, pro-m is out of business and i need a new one. I have called Procharger to see if they make a unit for my kit but the said i will have to go back to the stock set up. That means i will have to put my stock injectors in and probaly get it retuned. The car is in South Carolina were i'm station ,but i'm moving back to north Carolina. the car will not run. They say switch to a lightning mass air which i bought that first and i was told it would not work on my 98 gt's setup. I don't really have the money right now to through around because i get out of the military in a month. Thank you in advance. Randy
