Yeah, pretty much settled! Turbo is MUCH faster than the Whipple. Hp tuners is what the car is using. I'm not a tuner so I pick who I trust to do it and so far, they all use it. Im gonna try a new guy on this side if the country in a few weeks or so for a retune...let ya know how it goes. My opinion, if I had to do it over, I'd start with Holley stand alone vs factory p c m.
