My 99 GT has a vortech supercharger...blow through set up, inter/after cooled ,42lb injectors and cat back exhaust. It is putting out about 430 hp at wheels. I am wondering if the stock rear end is gonna hold up fine to that set up? i dont race it ever. Just highway driving and the occasional stomp to show off. It is also automatic. Do you think i need to replace the rear end and/or the tranny?

Thanks
