Good afternoon, on the 475 HP kit it states a new "plug and play harness is included", this is not stated in the 550 HP kit ad. Is the 550 HP kit a true plug and play as it relates to the associated wiring harnesses, or is there work that needs to be done to customize wiring harnesses and or plugs during the install?

  • One reason the 475 HP kit uses a plug and play harness is for CARB approval reasons. For this kit, the wiring harness will require some modification. The installation procedure for this is a bit complex, but the guide covers it pretty well for the experienced hand. While it hasn't been uploaded just yet, if you'd like to reach out to us we'd be glad to assist with an install guide if you'd like to get a better idea of the product's installation.

    SuperCharger phase 2

    Made a world of a difference, I had a 120 shot of nitous going into this at first but after I put the supercharger on, it's like all that power at once. Installment wasn't too difficult compared to some of the superchargers I've installed, after the dyno and time this thing was pushing close to 500HP. Deffiently worth it.
