FIC injectors are well known for their quality and accuracy

FIC injectors are well known for their quality and accuracy. But FRP's communication is second to none! Ryan specifically has the knowledge and patience to help customers achieve their goals. Add to that a large inventory of common parts on hand to facilitate fast shipping. Super happy!

FRP tune Was the exact thing needed for a Hemi 5.7-Jeep JK

FRP tune Was the exact thing needed for a Hemi 5.7 swap in a 2015 Jeep jk. The Hemi contained a 6.4 OEM cam. Also used the Nag1 transmission with the 392 torque converter. Spent a few hours with Ryan remotely. It was easy to accomplish as long as you do your homework and follow the pre suggested points given by FRP. I later reached out to Ryan with a small glitch in how the engine started. He sent me a quick tune up to the start settings and it popped off wonderfully. I’m extremely happy with my decision to bring my Jeep Speed Shop project to FRP. Will look in the future at their Hellfire 2.0 cam.

I’m not into horsepower. Just a guy that wants to fix his truck. the website has a really easy layout to find the parts you need. Really like how they offer full kits with everything you need and the customer service is excellent!
