Kevin does good work and has great cilia timer service, agreed. But to say it is the best place ever.....well, you just can't say that until you've been to the rest. Jeff at FAST, Cam at redline, Andy, Brandon, the list goes on.
In addition, anyone can have a single bad experience or screw their shit up tuning and blame the builder. Happens all the time. So, in trying not to be a dick, experiences are appreciated but the best advice it to visit with different builders. Develop a relationship with them. Understand what they can do for you and decide based on your own personal experience. Not mine or his or whoever else may chime in.
