Install it youself it is very easy, takes about 2-3 hours max. Nothing but simple wiring jobs and you're gonna need a steel braided fuel line to tap into the fuel unless you have a fuel rail, but you can get that from jegs. If you have any questions hit me up. It was a very easy install. Not worth to pay to have someone do it for you. Plus you feel so much better when you hit the juice knowing you did that yourself!!! I would recommend changing your plugs too. :gap: BTW 55shot is around 55HP yes your are right.
