that is the full package..
If you want the power only based on the build and price it looks to be around $7,000 for the S/C, Motor work and Tune.
Add the high pro brakes and suspension to the mix and that $17K become $30K real fast..
---
It appears to be to be pretty comparable to what I have seen, similar mods to a Chrysler/Dodge SRT is about $30K (forced induction, motor work, high-flo injectors, intake, exhaust, tune, brakes, suspension, etc)
I worked for GSM and NuFormz Racing for several years as a Mopar Tech (side job to my full gig as a Dealership Tech) and the pricing was very similar..
The only thing that really stands out to me is the 3/36 warranty, no other forced induction product I am aware of offers that.
