If you are on Facbook come see what Ford 5.0 customers say about our Custom Tuning. This includes Mustang and F150 5.0 people who have made the switch over to The Tuning Professionals at SSi Performance. Lately we have had a lot of people come over who were tuned with other companies. The comparison, feedback, and testimonials are most excellent. Great linear power, no flat spots, dead spots, or hesitations, perfect shifting, and improved mpgs are the usual comments. Come on over to the SSi Performance Group page on Facebook to see this and a whole lot more of what we do. The pics below are just a few comments and a 0-100 Video.
