I'm using 370s
Eh, the whole ITB setup is a touchy situation, dont forget this is my daily driver and I know that alot of people run into idling issues which I'm most likely gonna run into with the Pro1's anyway but I just dont think they'd be good for daily driving and for the money I dont think they're worth it for the power they make. Now if I ever buy a second car and have alot of money lying around then sure why not.
