        Incredible S/C kit

        This is an amazing mod. HUGE horsepower gains will have you well over 450 at the rear wheels. The kit is very complete and high quality. All went together very well. AmericanMuscle notes (even after I brought it to their attention) that the kit comes with a flash programmer, which is incorrect. After several calls to AM and Ford Racing I ended up having to send my PCM to Whipple. No big deal, but it'd be nice if AM would list it correctly so you know what you're getting (especially since this issue has been brought to their attention...). In any case, this thing sounds GREAT, very loud whine. It feels great and pulls like crazy. It looks great and everything fit my GT as it was supposed to. Highly recommended

      Can I use this kit with stock engine internals ? Thanks.

      • This kit will work with the factory internals in your Mustang, however the safe limit on the stock pistons and rods is around 450hp, so it would be recommended to look into an upgrade if you were driving the car hard.

      Cams, tune and hood fit Will this unit work with the Comp Cams Mother Thumper 2 cams or would I have to go back to the stock cams? Does tis unit come with a tuner and tune or would I need a to use my SCT and tune from American Muscle? Does this unit fit under the stock hood?

      • Yes it can be tuned to work with Mother Thumper 2 Cams. Yes it's equipped with a tuner package deal and No unless you prefer to use your preowned tuner and work it out with AM. Yes it will fit under stock hood easily.
