From the factory, Ford programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in search of more power. That is why a custom tune file is so important, by optimizing the air/fuel ratio, adjusting ignition timing and tweaking variable cam timing, a VMP Tuning Custom Tune will squeeze out the extra power your aftermarket performance mods have to offer. Curve Gains of 24 RWHP / 24 RWTQ have been seen on bone stock 5.0L Mustangs with a VMP 93 octane tune.
