i spoke to him just couple days ago i am still trying to verify it will bolt up with no issues. It would not help you much at idle as i think idle amperage will be around 100-120 amp. I am not sure what the stock puts out at idle as it is 120amp probably at a higher rpm where the high output will put out around 180-260. If the stock only puts out around 80amp at idle and the high output puts out 120 at idle and 200 at higher rpm than an alt will help you out. the extra amperage will not hurt your car but make sure you replace all your wires with 4agu or 2 agu if you are gonna go with a high output alternator.
