I have a Gude kit , it fits just fine , its all you idiots out there not using the proper tuning . You need SCT or Sniper tuning to take out all the timing and reconfigure the mapping of your computer . Dont knock something till you try it . I have a full stage 2 gude kit , all 2" piping and full 2.5 inch exhaust . In order to have a good build up of pressure and have no turbo lag , the piping must be small , as well as the turbo , my wastgate will not open till its at 13lbs, and my BOV is set at 7lbs ,and my boost controller is set at 13lbs so there is absolutely no hesitation . So go ahead and talk bad about Gude , where's your turbo kit ?
