I need a tune. I hear SSI is great but everything I look up is horrible. Mainly with them blowing up ecoboosts. But not much input on GM. I have a 03 Silverado 5.3 4x4. 4.88 gears, stage 2 BTR cam, long tube headers, TBSS intake. Closest shop to me is about 2 1/2 hours away so getting a programmer and having a custom tune is more convenient for me. Any help would be greatly appreciated.
