Thought we should chime in
We "held back" some boost cause we know lots of people don't want to go through the trouble of doing custom tuning etc. So we provide a 100% bolt on kit that makes +50hp & 51lbft at the wheels... no tuning required. Keep in mind that our kit comes with pulleys that actually fit your belt in addition to the inclusion of a 255lph fuel pump, intake kit, and ALL the pieces you need. No running to the hardware store to buy wire, hose, etc... not countless other modification you might make. All things considered, our sale price (often goes on sale for $2000 if you wait) is actually cheaper than the other kit if you bought the pump, intake, etc (which you probably will).
We also support our product with various add-on products. We will have our intercooler kit, 8psi kit, and other accessories for this product available soon.
Hope that helps comparing apples to apples.
