Amelia ★★★★★ Oct 22, 2026

The dual-speed controller is a game-changer for daily driving versus track days—just flick a switch and you're set. My 4.6 idles smoothly now with plenty of headroom for future mods.

Christopher ★★★★★ Oct 21, 2026

Installed this in my 2005 Mustang GT and the dual-speed controller is a nice touch for dialing in pressure without messing with extra parts. No issues with the in-tank fitment using the included install kit.

Robert ★★★★★ Oct 20, 2026

This kit gave me much better control over fuel delivery than the old setup, and the included install hardware saved me a trip to the store. The two-speed controller makes it easy to dial in flow for both cruising and the track.
