Tuner tuned my car and it is trash with 1000 issues, asked him to return the car to stock after a month and he says he lost the file. If anyone could share the stock file, I could give it a try. Using HP tuners.
Hello there. I'm running stock headers with no catalytic converters with Borla Pro XS mufflers. I'm thinking to go with electric cutouts before the H pipe but will it hinder performance? Is it going to break/hurt anything? Sorry I'm just learning with the car stuff, so please excuse me. Thank...
