Nice to have a warranty.
Was planning on putting some DR-500's in my car soon on stock injectors with a walboro or supra pump but they sold to soon. Had money ready and all. Matt M. ran a 11.5 on stock fuel on 91 octane @ 5200ft with them but I'm not much of a numbers guy as I never go to the track and don't really have a need to spit out my numbers. Right now I am near full BPU which is still a good mid to high 12 second car for a good driver as a measurement. Right now, I think I am going to do some clean aesthetic mods which are still pricey as all hell.
