THANKS , I'm very pleased with it . I was really impressed with the power of this especially for having 20" wheels . 255-60 hp is pretty darn good , shoot thats more than 302 & 4.6 mustangs . yes it does recommend 89 octane. I plan on doing some mods to it . I just dont know where to start . it will be cool if they made a supercharger for these things. Fiesta dodge here in san antonio does have 2 RTs in stock now which is an inferno red & black . I will be posting more photos
