Professionalism, Knowledge and Experience made my project a success! Thank you Tim and FSI ! 2000 Silverado 5.3

On 1/14/2026 Dustin G had this to say:
Had some friends who spoke highly of Tim at FSI so I called and spoke with him a few times about the build I was doing on my Silverado. He told me he could get it handled and make my integration of parts work and sure enough he did . Nice 70+ hp gain over stock with my build with stock internals except for the cam. Truck runs fantastic and Tim made it all worth it! Testimonial written by Dustin G on this site.
