        Will this work with the Ford performance power pack?

        • The Flowmaster Delta Boost Performance Tuner should work just fine with the Ford Power pack! It should simply add an approximate boost of around +4psi but it shouldn't cause any issues

        Installing this, will it show up as a tuner does for warranty work?

        • The Flowmaster Delta Boost Performance Tuner will install inline with the Boost sensor, and would most likely cause warranty issues, as this is causing an increase in boost.

            Great power gains

            Ypu can definitely feel the extra 20-30hp. acceleration did not improve much. Pulls form 40-60mph are amazing. Be careful not to hit 120 by accident.

            What a transformation

            This little red module from Flowmaster is quite a product. It installed so easy n gassy. It also fixed my issue I had with my Treadstone Intercooler boost sensor problem. Due to the sensor being mounted on their cold pipe the OEM plug was to short to work but the Flowmaster booster plugs into that sensor and into the OEM plug and has about 10" of slack. Sport mode delivers 2lbs more boost and race mode delivers 4lbs of whiplash power. With all my mods u am Amazed!!!! This little red box is a must for the gains and fun it'll transform your mustang ecoboost into!!!! Downloading app onto your phone is very easy as is using the Flowmaster booster app.

            You can feel the 4 psi gain! I didn't think that it would make that big of a difference...
