I'm sure a few of you are familiar with Switzer Performance. They're more involved in the GTR scene however one of my customers who just had his GTR built by them mentioned they are getting into Raptors as well. Their tune is pictured below however they will be releasing upgraded turbo's in the next few months from what I'm told. The ones they've been testing are said to be putting down 525-550WHP. Figured I'd open a thread to keep track of the progress.
