Steven G. ★★★★★

Was a bit nervous about the install, but it dropped right into the stock assembly with no modifications needed. Fuel pressure is spot-on now and the engine pulls noticeably harder through the mid-range.

Sophia ★★★★★

My tuner was impressed with how easy it was to set up the direct-fit module, and my fuel trims are now rock solid even under boost.

George M. ★★★★★

Popped this in over the weekend and the fuel pressure held steady through my first full tank of e85. The included harness made wiring a breeze compared to other pump modules I've dealt with.
