We put the latest H&S Hot File for the 6.7 Ford into our truck and then the new WarHammer tune from Spartan. The new Spartan WarHammer tune has about 30HP on the H&S tune per our dyno results. Let us know if you have any questions, we have both units in stock and ready to ship out along with many different exhaust options.
