The Precision Turbo option has delivered excellent performance for us so far. This is a much more aggressive setup. Fuel economy is down some but maybe that's because I can't keep my foot out of it. It truly is sports car fast. I am trying to get the time to make some video of the setup so people can experience what the system looks like piece by piece and what it sounds like. Prodigy Performance has delivers best in class performance. Videos soon to come. Do some research on Precision Turbo. All of the big names in High HP run Precision units. Garrett in my opinion is considered a reliable workhorse where as Precision is considered a more Extreme performance Version. IMO
