It was put on hold because the original test car backed out and they have been waiting for someone to step up to fill the rest of the testing.
Best part is a lot of the work has been done, they had the kit on the car so it was more fine tuning by the looks of it. Making sure pieces fit properly, tuning, checking for possible mistakes.

You and me both... I'm afflicted with refreshing the forum every 5 minutes, checking my email inbox and scouring the forum haha. It's a test of patience and things are just getting started. I'm not sure what fine tuning still needs done, but my car will be with them for 9 months. They most likely won't need nearly that kind of time to complete it.

Other factors that may come up is my car is very very far from stock. Some of the parts I have do need to come off. The LTH's and full exhaust will reduce the amount of pressure running in the system and may have to play with pulley's, belts and housing sizes to find what works best for the application. I also threw radiators, new hoses, a Motordyne manifold, brakes, a lot of extra stuff. They can try a host of combinations that will help them anticipate what a customer needs with stuff I already bought. I even supplied a brand new resonator for my Y pipe, they can theoretically test the difference in power and back pressure between that and a HFC. It's not a 100% to having two resonators and HFC's after the stock header, but close enough.

9 months also leaves room for them to take more of my money haha. I could go for some strengthened internals and their traction control system. Not sure how the Wife would respond to that, so I'm just gonna leave the that alone
