He won't even respond, he just trolls and responds garbage with no information to back anything up. And with all the other out right wrong 05+ mustang answers he posts, he should stick to cars he actually owns.
Even used supercharger kits, go for good money. Every sap thinks they can get all their money back out of their used kit, if they spend 7k total installed they want 6k back out of it no installation.
The real bonus of building the kit yourself is you can purchase your parts in steps and never need 4k plus in your hand at one time. You could build your kit over a few months.
And you get to chose the parts you want! Want an upgraded heat exchanger? Spend the money on the afco exchanger without wasting money on the gt500 stocker first. Don't want to spend on gt500 fuel pumps , get a boost a pump instead. The list is endless.:bigthumbsup
