You will be happy with the kit. I went down the same path but VMP and Justin had done my Shelby KR and Boss 302LS and both made 720whp and 730whp on 91 pump gas with the TVS.
So in the end I am very happy with my raptor build. I wish I had more power but who doesnt right. We actually tested my truck about an hour ago and was able to do 0-60 in 6.1 seconds with two of us in the truck, snug top shell, bed full of tools, hi lift etc, warn 9.5xp in the front bumper and a set of general 35x12.5 X3's so I cant complain. Not to mention im at 5500ft with a DA in the 6500 range.
