Newbie to this. Was thinking of getting the PPK but w/ the delay, minor power boost (20hp) and anticipated cost, thinking this might be a better route to take.
What should I know before going this route? Engine failures, warranty issues (is it really untraceable), reliability, etc?
Would appreciate a view on this.
Also - what is involved in the install. The PDF isn't clear at all on the JB website. Really need to know exactly what needs to be plugged into what. I see like 9 connections on the harness, and yet it indicates that the F30 only needs 2 connections???
