A tune is new software for your truck's engine computer, loaded through a handheld tuner that plugs into the port under the dash. MPT's 93 octane PR-X tune for the 2015-2017 5.0L V8 changes fuel and spark management to safely pull more power from the stock engine. Multiple octane and use-case versions are available; this row tracks the flagship 93 octane calibration.
why this one — MPT shows a real dyno comparison for this tune: 322 to 377 horsepower at the wheels, about 55 hp and 85 lb-ft gained on 93 octane. Tested numbers on the maker's own dyno beat the estimated claims most tunes ship with, and $300 is entry-level money for that gain.
MPT dyno session, stock (322hp/324tq) vs 93 PR-X tune (377hp/409tq) at the wheels, per product page.
